and teeing device 102 depicted in fig1 . however , in such embodiments , a standard or specialty golf tee 232 is seated into the hole 235 defined in the retrieval portion 216 before the retrieval and teeing device 202 is dropped proximate a desired teeing location . the retrieval and teeing device 202 may then be manipulated into an upright position and a golf ball placed upon the golf tee 232 using the positioning device 104 as generally described above . fig1 depicts a positioning device 104 being used to mark the position of a golf ball 111 using a washer - shaped ball marker 195 in accordance with one embodiment of the present invention . upon reaching a golf green , a golfer simply drops the washer - shaped ball marker 195 proximate the ball location and inserts the interface portion 106 of the positioning device 104 into the grip hole 114 of the golfer &# 39 ; s club ( e . g ., wedge , putter , etc .). the golfer then grasps the head of the golf club and pushes the golf ball marker 195 into place behind the golf ball 111 using the hook portion 110 or outer edge of the cradle portion 108 of the positioning device 104 . when it is time for the golfer to putt , the golfer may retrieve the golf ball marker 195 by inserting the hook portion 110 of the positioning device 104 into an aperture 196 defined in the golf ball marker 195 and withdrawing the marker 195 upwardly along arrow b as shown . in another embodiment of the present invention a portion ( e . g ., the hook portion ) of the positioning device 108 may be magnetized for use with a metallic golf ball marker 195 . in such embodiments , the ball marker 195 could be manipulated into place on the ground using a non - magnetized portion ( e . g ., the cradle portion ) of the positioning device 108 and retrieved using the magnetized portion of the positioning device 108 . fig1 and 14 depict a ball mark repair device 350 structured in accordance with another embodiment of the present invention . the depicted ball mark repair device 350 may be alternatively referred to as a turf repair tool . for purposes of the present invention and appending claims the term “ ball mark ” refers to a divot , indentation , or other turf imperfection that occurs during golf as a result of impacts with the ground . although most effective for repairing ball marks it will be apparent to one of ordinary skill in the art that ball mark repair devices structured in accordance with various embodiments of the present invention may also be used to repair divots created when a golfer swings a golf club or other turf imperfections . the depicted ball mark repair device 350 includes a lever portion 352 , a base portion 354 , and a finger portion 358 . the finger portion 358 includes at least one finger 357 that is adapted to be inserted into a putting green or any other surface having a ball mark 360 that a golfer wishes to repair . the depicted embodiment includes three fingers 357 . the base portion 354 includes an interface portion 356 that is configured to be received by the air relief hole 114 of a conventional golf club grip 113 , as similarly described above with respect to other embodiments of the present invention . in the depicted embodiment , the interface portion / air relief hole interface also includes a durable , weather - resistant , hook - and - loop fabric fastener as generally described above . the depicted hook - and - loop fabric fastener includes a first portion 345 comprised of a hook material and a second portion 355 comprised of a loop material . in the depicted embodiment , the first portion 345 is attached to the base portion 354 of the ball mark repair device , and the second portion 355 is attached to the end 117 of a golf grip 113 as shown in fig1 and as similarly described with respect to the embodiment depicted in fig8 . fig1 shows usage of the ball mark repair device 350 in accordance with various embodiments of the present invention . upon reaching a putting green ( or any other turf surface ) having a ball mark 360 that a golfer desires to repair , the golfer simply inserts the interface portion 356 of the ball mark repair device 350 into the air relief hole 114 of the golfer &# 39 ; s putter ( or other golf club ). upon insertion of the interface portion 356 into the air relief hole 114 , the first portion 345 of the hook and loop material engages the second portion 355 of the hook and loop portion material in order to secure the ball mark repair device 350 to the end 117 of the grip 113 , and to keep the ball mark repair device 350 from rotating about the interface portion 356 . also , in this position , the lever portion 352 rests against a portion of the grip 113 adjacent the end 117 of the club as shown . the lever portion 352 is intended to provide leverage during usage of the ball mark repair device 350 . thus , in various embodiments , the lever portion 352 may take a variety of differing structures including structures that enhance the leverage provided by the lever portion 352 . for example , in one embodiment the lever portion may define a curved region adapted to complement the curvature of the grip 113 . in another embodiment , the lever portion may define a rib or other similar feature located at the top of the lever for creating an upwardly located contact point and thereby enhancing the leverage available when using the ball mark repair device . a golfer manipulates the ball mark repair device 350 by grasping the head of a golf club and pointing the golf club grip 113 and , thus , the ball mark repair device 350 , toward a ball mark 360 that is to be repaired . the golfer then inserts the fingers 357 of the ball mark repair device 350 into the ground 128 near the ball mark 360 . the golf club is then moved against the lever portion along the direction generally defined by arrow c . when the golf club is moved in the direction of arrow c , the lever portion 354 of the ball mark repair device 350 provides leverage against the grip 113 such that the fingers 357 of the ball mark repair device 350 move in the direction generally defined by arrow d . this process may be repeated around the perimeter of the ball mark 360 as will be apparent to one of ordinary skill in the art . in this regard , the ball mark repair device 350 may be used by a golfer to repair a ball mark 360 without bending over . in other embodiments , the ball mark repair device may be structured as set forth above ; however , the interface portion 356 may be omitted . in such embodiments , the first portion of the hook and loop material would continue to engage the second portion of the hook and loop material thereby securing the ball mark repair device to the end of the golf club grip . the lever portion would therefor rest against a portion of the grip adjacent the end of the club as described above . in this regard , the lever portion would provide leverage for manipulating the tool during usage of the ball mark repair device . should additional stability be required a more robust hook and loop material may be used . alternatively , in other embodiments , a first end of a double - sided hook and loop strap may be affixed to the back surface of the lever portion ( i . e ., the surface opposite that which contacts the golf club grip ). a second end of the double - sided hook and loop strap could then be wrapped around the golf club grip such that the double - sided hook and loop strap overlaps and thereby adheres to itself . in still other embodiments , the lever portion of the ball mark repair device may be formed to define a ring or partial ring that is structured to slideably receive the golf club grip as it is positioned to seat against the hook and loop surface of the first portion of the ball mark repair device . many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings . therefore , it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims . although specific terms are employed herein ,
