This Jaxa tool, I think, is similar or the same as mine I bought years ago at my local swap meet.  A no brand Jaxa, made in India, that came in a plain white box with the bits in a sealed plastic bag.  The Chinese made versions appear to come in more of a presentation box and the tool itself may even look better than India version but IMO it's an inferior tool.

The biggest differential are the bits, India versions have the bits fit the tool with a fair amount of precision while the Chinese versions have a good deal of slack between the bit and the socket of the tool.  Appearance wise the India version bits appear to have the proper degree of taper at the end of the bit opposite the head, the end that is inserted into the socket of the tool.  Chinese version has a taper that looks more like a cone, a very imprecise fit.

Questionable structural strength of the Chinese version.  Jaxa tool body consists of two plates of steel held together by bolts and spacers.  I've seen and handled Chinese versions that didn't use steel spacers between the plates, instead nuts were used on the threaded bolt/screws to keep the plates aligned.  Chinese version use Phillips head screw/bolts while the norm is slotted.

Overall the India made Jaxa is more like the real Swiss made tool.  The India version lacks the precision and the friction at the adjustment handle.  Friction is needed at the adjustment handle to help keep the adjustment in place while the tool is in use.  Swiss version uses a washer between the body of the tool and adjustment handle.  Getting a washer in the same place with the India version is difficult but has been done.

Removing the shaft from the handle is risky because damage to the shaft could result.  Using a washer that has the proper size for the shaft will not work unless the shaft is separated from the handle.  The shaft has an enlarge area that rides between the two halves of the body to keep the shaft in place.  The washer needs to be large enough for the enlarge area of the shaft to fit then the washer is folded on two sides to better fit the shaft.  Not an easy thing to do but it works.  I used a brass washer common in a plumbing washer kit.  Used a Dremel tool to thin and deburr the washer and various pliers to shape the washer.  Then applied synthetic grease.  Lube is needed because the modification made the handle so tight it would hardly budge.

Now I have a Jaxa tool almost as good as my Swiss version.
