as has been mentioned , the present description is about improvements in pull hoes . embodiments are now described in more detail . fig2 is a conceptual side view of a hoe 200 made according to embodiments . hoe 200 is configured for a user to hoe soil , such as in a garden . an embodiment of a hoe based on fig2 can also be called a soft dig pull hoe . hoe 200 includes a handle 220 . handle 220 has a user end 222 that is configured to be grasped by the user . handle 220 also has a distal end 224 . handle 220 has an overall length that can take any dimension . in some embodiments the length is less than 2 ′, for use primarily when kneeling . in other embodiments , the length is over 3 ′, for use primarily when standing up . distal end 224 , and possibly entire handle 220 , is made from at least a first material , such as wood , plastic metal and so on , or a combination of the first material with another material . the first material has a first consistency , for example as can be manifested by macroscopic properties of distal end 224 . for example , different types of wood have different consistencies , depending on the wood itself . further , different types of metal have different consistencies , and so on . hoe 200 also includes a connection member 270 . embodiments of connection member 270 are described in more detail later in this document . connection member 270 is directly attached to distal end 224 , or is coupled to it , for example via one or more additional components . connection member 270 can be made from at least a second material that has a second consistency . typical candidates for the second material include steel , as will be seen in more detail below . the second consistency can be different from the first consistency of distal end 224 . for example , even if both connection member 270 and distal end 224 were made out of steel , they could differ in macroscopic properties such as tensile strength , and so on . hoe 200 moreover includes a blade 280 . blade 280 has a working portion 282 that is configured to contact the soil . working portion 282 can be made as is known in the art , or as in further embodiments . blade 280 also has an attachment portion 284 . attachment portion 284 is directly attached to connection member 270 , or is coupled to it , for example via one or more additional components . attachment portion 284 , and possibly entire blade 280 , can be made from at least a third material . the third material can be steel or other material hard enough to dig into the ground , upon impact . the third material has a third consistency , which can be different from the second consistency of connection member 270 . for example , even if both connection member 270 and attachment portion 284 were made out of steel , they could differ in macroscopic properties such as tensile strength , and so on . in particular , the second material could be more easily flexible than the third material . because of the flexibility , the impact transmitted from blade 280 to handle 220 can be reduced . fig2 is conceptual , and not limiting . for example , connection member 270 is shown simply next to handle 220 and blade 280 , without showing the manner of coupling of attachment . sample such manners will be described later in this document . fig3 is a top view of a steel spring 370 . steel spring 370 can be used as connection member 270 in fig2 . steel spring 370 can optionally include one or more steel spring holes 376 , 377 , for attachment as will be seen later in this document . steel spring 370 can be flexible and resilient . the flexibility is what reduces the impact transmitted to the user , while the resilience permits the original shape to be restored . after some experimentation , good dimensions for steel spring 370 were found to be as follows : thickness ⅛ ″. the thickness is perpendicular to the drawing of fig3 . width : 1¼ ″. the width is seen as height , i . e . the short dimension , in fig3 . length : 7 ″. the length is the long dimension in fig3 . steel spring holes 376 , 377 can be large enough to allow a ¼ ″ bolt through them . a steel spring can be attached to a handle in a number of ways . an example follows . fig4 shows a portion of a handle 420 , which could be as handle 220 . handle 420 has a distal end 424 , which could be as distal end 224 . handle 420 has a handle opening 425 at distal end 424 . a side view of a steel spring 470 is shown , which could have similarities with steel spring 370 . steel spring 470 is partly received in handle opening 425 . accordingly , steel spring 470 can flex , thus being able to occupy positions such as positions 471 , 472 . positions 471 , 472 are shown spaced widely , for clarity . in reality , while steel spring 470 might flex , it might not flex as widely as positions 471 , 472 suggest . in some embodiments , handle 420 has at least one handle hole 426 . where , as here , handle hole 426 encounters handle opening 425 , handle hole 426 may extend past handle opening 425 until it exits handle 420 . steel spring 470 has at least one steel spring hole 476 . in addition , the hoe would further include a bolt 444 , inserted through handle hole 426 and steel spring hole 476 . bolt 444 can be approximately ¼ ″ diameter . moreover , a nut 445 can be screwed on to bolt 444 . after screwing , nut 445 can become more permanently attached to bolt 444 , for example by soldering . fig4 shows only a single set of a handle hole 426 , steel spring hole 476 , bolt 444 and nut 445 , but that is only for clarity . in reality , two sets could be used , and so on . for example , steel spring 370 has two steel spring holes 376 , both of which would be inserted in a handle opening . a challenge is that , implementing handle opening 425 and handle hole 426 removes material from distal end 424 , to which stresses will be applied by steel spring 470 from the digging motion . to preserve the structural integrity of distal end 424 in the face of such stresses , embodiments of a hoe could further include a metal pipe section 450 . pipe section 450 can surround at least a portion of distal end 424 . as such , pipe section 450 would also surround at least a portion of steel spring 470 that is received within handle opening 425 . in fig4 , pipe section 450 reaches , from the sides of handle 420 , up to steel spring 470 . such is preferred but not necessary . where bolts are used , pipe section 450 can accommodate . for example , it could have one or more pipe holes 456 , and bolt 444 can be inserted through one or more pipe holes 456 in addition to the other holes mentioned above . pipe section 450 will necessarily have some thickness above and beyond the thickness of handle 420 . that may be not aesthetically nice , plus it may pose a slight hazard to the user . accordingly , in some embodiments , pipe section 450 has the same diameter as handle 420 and is flush with it . for manufacture , a portion of distal end 424 can be beveled down before pipe section 450 is applied , as will be seen later in fig1 . fig5 shows a blade 580 , which could be as blade 280 . blade 580 has a working portion 582 , which could be as working portion 282 . blade 580 also has an attachment portion 584 , which could be as attachment portion 284 . attachment portion 584 has at least one , here two , attachment holes 586 , of which only one is indicated so as not to clutter the drawing . a side view of a steel spring 570 is shown , which could have similarities with steel springs 370 and 470 . steel spring 570 has at least one , here two steel spring holes 577 , of which only one is indicated so as not to clutter the drawing . a hoe made as in fig5 also includes at least one bolt 544 ; in fact , there are two , of which only one is indicated . the indicated bolt 544 is inserted through attachment hole 586 and steel spring hole 577 . moreover , a nut 545 can be screwed on to bolt 544 , similarly to what was described above . fig6 is a perspective view of a coil spring 670 . in embodiments , coil spring 670 serves as connection member 270 of fig2 . an example is now described . fig7 shows a portion of a handle 720 , which could be as handle 220 . handle 720 has a distal end 724 , which could be as distal end 224 . a side view of a coil spring 770 is shown , which could have similarities with coil spring 670 . coil spring 670 is attached to distal end 724 via a joint 777 , which can be made of steel . accordingly , coil spring 770 can flex , to absorb shock . in the embodiment of fig7 , a portion of distal end 724 actually internally extends within a portion of coil spring 770 . the dimensions are such that the desirable amount of flexing is permitted . this internal extending is not necessary to practice the invention , and joint 777 can alternately be located more to the right in other embodiments , than is shown in fig7 . fig7 shows a blade 780 , which could be as blade 280 . blade 780 has a working portion 782 , which could be as working portion 282 . blade 780 also has an attachment portion 784 , which is soldered to spring 770 . fig8 a is a perspective view of a hoe 800 made according to embodiments . an embodiment of a hoe based on hoe 800 can also be called an earth - gripping pull hoe . hoe 800 includes a handle 820 , which could be as handle 220 . handle 820 has a user end 822 , which can be configured to be grasped by a user , as user end 222 . handle 820 also has a distal end 824 , which could be as distal end 224 . hoe 800 also includes a blade 880 . blade 880 has an attachment portion , which is not indicated separately . the attachment portion is coupled to distal end 824 , which can be implemented in many ways . for example , the attachment portion can be attached to distal end 824 . or a connection member can be coupled between the distal end and the attachment portion , as described above , starting from fig2 . blade 880 further has a working portion configured to contact the soil , and which is not indicated individually . the working portion includes at least a first section 881 , and a second section 883 that is at a gripping angle from first section 881 . the gripping angle occurs because , equivalently , sections 881 and 883 are at different angles with respect to a portion of hoe 800 , such as , for example handle 820 . the gripping angle can be implemented by starting with a single metal segment and bending it . the gripping angle can be defined from sides of the working portion that face handle 820 , which would be the inward side of the bending and therefore have a value of less than 180 °. the outward side of the bending would therefore have a value larger than 180 °. of course , a value of 180 ° would correspond to no bending at all . the gripping angle can have the result that hoe 800 is not driven out of the earth , upon breaking up a clump of soil in front of the blade 880 . rather , section 883 tends to remain dug in the soil , thanks to the gripping angle . for embodiments such as that of fig8 a , the gripping angle can have a value of less than 170 °. a good value is approximately 135 °. referring briefly to fig8 b , the concept of the gripping angle is now explained in more detail . in the example of fig8 a and 8b , sections 881 , 883 are large enough to include practically the entire working portion . moreover , sections 881 , 883 are substantially flat , and the entire transition from section 881 to section 883 takes place along a spine 888 , which can thus be a crease , or a fold in the single metal segment . in that case , section 881 lies along line 807 and section 883 lies along line 808 . gripping angle 811 can be defined as shown , as the angle subtended between lines 807 and 808 , and from sides of the working portion that face handle 820 . in other embodiments , sections 881 , 883 need not be large enough to include the entire working portion . they can be infinitesimally narrow , while the working portion is bent , and far from each other along the working portion . an example is now described . fig8 c is a side view of salient aspects of a hoe 835 with a handle 839 and a working portion that is bent . a first section 841 is infinitesimally small , near handle 839 , and is on a plane , or has a tangent along line 847 . a second section 843 is infinitesimally small , near the end that digs , and is on a plane or has a tangent along line 848 . the transition from first section 841 to second section 843 takes place rather gradually . gripping angle 851 is defined from lines 847 , 848 , and from sides of the working portion that face handle 839 . fig9 is a perspective view of an earth - gripping hoe 900 . hoe 900 includes a handle 920 , which could be as handle 220 . handle 920 has a user end 922 , which can be configured to be grasped by a user , as user end 222 . handle 920 also has a distal end 924 , which could be as distal end 224 . hoe 900 also includes a blade 980 . blade 980 has an attachment portion , which is not indicated separately . the attachment portion can be coupled to distal end 924 . this coupling can be implemented in many ways . for example , the attachment portion can be attached to distal end 924 . or a connection member can be coupled between the distal end and the attachment portion , as described above , starting from fig2 . blade 980 also has a working portion that is configured to contact the soil , and which is not indicated separately so as to not clutter the drawing . the working portion has sections 981 , 983 , which are joined at a spine 988 . the working portion also has a mouth 986 according to embodiments . for purposes of this description , a mouth is an opening in the working portion of a hoe &# 39 ; s blade . a mouth can be made by a cutout in the working portion . mouth 986 is bounded by a perimeter 985 , of which only two sides are indicated . mouth 986 is configured to allow the soil to flow therethrough , according to a flow 999 , when blade 980 is in the soil and the user pulls handle 920 . accordingly , mouth 986 reduces the resistance the user faces when using an earth - gripping hoe such as hoe 900 . in the particular case of fig9 , at least a portion of perimeter 985 is coextensive with spine 988 . this has the benefit of reducing resistance , given that section 983 can remain dug in the earth . it is not necessary however that a mouth be implemented that way , or even in only one of sections 981 , 983 . in fact , a mouth can be implemented according to embodiments where a hoe is not earth - gripping . an example is now described . fig1 is a perspective view of a hoe 1000 made according to embodiments . hoe 1000 includes a handle 1020 , which could be as handle 220 . handle 1020 has a user end 1022 , which can be configured to be grasped by a user , as user end 222 . handle 1020 also has a distal end 1024 , which could be as distal end 224 . hoe 1000 also includes a blade 1080 . blade 1080 has an attachment portion , which is not indicated separately . the attachment portion can be coupled to distal end 1024 . coupling can be implemented in many ways . for example , the attachment portion can be attached to distal end 1024 . or a connection member can be coupled between the distal end and the attachment portion , as described above , starting from fig2 . blade 1080 also has a working portion 1082 , which is configured to contact the soil . working portion 1082 can be flat , or bent as described above . working portion 1082 also has a mouth 1086 , which is bounded by a perimeter 1085 . mouth 1086 is configured to allow the soil to flow therethrough , according to a flow 1099 , when blade 1080 is in the soil and the user pulls handle 1020 from user end 1022 . working portion 1082 further has an optional tooth 1087 . tooth 1087 can protrude such that the soil flowing through mouth 1086 , according to flow 1099 , is cut by tooth 1087 . cutting would be from the top , given the position of the tooth . the tooth can also be in other positions . cutting can condition the soil better . optionally and preferably , tooth 1087 terminates at a sharp point , for cutting better the flow 1099 of flowing soil . moreover , the working portion could include further one or more teeth , and so on . in the embodiment of fig1 , tooth 1087 is a feature of perimeter 1085 by which mouth 1086 is bounded . in such cases , the tooth can be implemented economically by proper design of the perimeter . in other embodiments , a tooth can be implemented by attaching a nail or equivalent structure next to the mouth . features of a tooth are now described more rigorously , so as to prevent confusion . if a mouth were merely rectangular or circular , no feature would protrude towards the flow of soil , so as to cut it . a tooth , however , protrudes that way . in the embodiment of fig1 handle 1020 is oblong . in fact , it is often a rod . handle 1020 defines a handle axis 1021 along its length . fig1 shows a geometric plane 1121 . plane 1121 is perpendicular to handle axis 1021 of fig1 . fig1 shows projected perimeter 1185 , which results from projecting entire perimeter 1085 onto plane 1121 . from this projection , tooth feature 1087 becomes projected tooth feature 1187 . a point 1101 in tooth feature 1187 is a place where tooth feature 1087 has becomes projected . a test line 1107 has the attributes that it is within plane 1121 , and is tangent to projected perimeter 1185 at point 1101 . in some embodiments , a test line with the attributes of test line 1107 intersects projected perimeter 1185 at one more point 1111 where tooth feature 1087 is not projected . the specific attribute arises because projected tooth feature 1187 protrudes towards the center of projected perimeter 1185 . it will be appreciated that this would not happen if projected perimeter 1185 were circular or oval — in such cases a test line would leave the entire projected perimeter on its one or other side . a tangent is not defined where projected perimeter 1185 is a point . fig1 is a perspective view of a section of an earth - gripping hoe 1200 , made according to embodiments . hoe 1200 includes a handle 1220 , which could be as handle 220 . handle 1220 has a user end 1222 , which is not shown . handle 1220 also has a distal end 1224 , which could be as distal end 224 . hoe 1200 includes a pipe section 1250 , which could be as pipe section 450 . a portion of distal end 1224 has been beveled down , so that the outer surface of pipe section 1250 is flush with handle 1220 . hoe 1200 also includes a steel spring 1270 , which can be made as described above , with reference to steel spring 370 . steel spring 1270 can be inserted in a handle opening of handle 1220 that is under pipe section 1250 and not visible , but similar to what was described above with reference to fig4 . steel spring 1270 is retained attached to handle 1220 via bolts 1244 that go through pipe section 1250 . hoe 1200 further includes a blade 1280 . it will be appreciated that blade 1280 can be made from a single sheet of steel , properly bent and cut . blade 1280 has an attachment portion 1284 . attachment portion 1284 is attached to steel spring 1270 via additional bolts 1244 . blade 1280 also has a working portion , which is not indicated separately . the working portion includes a first section 1281 , and a second section 1283 that is at a gripping angle from first section 1281 . the entire transition from first section 1281 to second section 1283 takes place along a spine 1288 . the working portion also has a mouth 1286 , which is bounded by a perimeter 1285 . the working portion further has a tooth 1287 within mouth 1286 . this description includes one or more examples , but that does not limit how the invention may be practiced . indeed , examples or embodiments of the invention may be practiced according to what is described , or yet differently , and also in conjunction with other present or future technologies . reference to any prior art in this specification is

, features and steps or operations , which are regarded as novel and non - obvious . additional claims for other such combinations and subcombinations may be presented in this or a related document .
a hoe includes a handle and a blade . in some embodiments , the handle and the blade are connected via a connection member . the connection member permits flexing , which reduces how much shock is transmitted to the user with digging motions . in some embodiments , the blade includes one or more sections at different angles . the different angles accomplish a gripping effect , which reduces how much the hoe is driven out of the ground , as it is being pulled . accordingly , fewer interruptions and digging motions are needed to cover an area , which one permits to finish faster . in some embodiments , the blade has a mouth that permits some of the soil to flow through it , as the hoe is being pulled . the flow may reshuffle the soil . optionally , a tooth protrudes such that it further cuts the flow of the soil .
