The version 2 sharpening jig was okay but it was flawed in several ways. Some of the issues were due to lack of proper material/tools. The angle brackets were simply not ridgid enough to eliminate all unwanted movement. This could be fixed if I had access to welding equipment (and knew how to operate it) The size of the round knife blade itself also causes problems as it flexes if you press too hard while sharpening.
The universal joints are also a bit loose and the current 3d printed parts are also not without play.
All of these issues could be fixed but one thing that would be hard to change is the fact that the pivot point is not in the center of the blade. This causes the bevel angle to change from the points to the top of the knife. With the current design we a looking at something like 5 degrees which is quite a lot.
The need for a new jig came as I purchased a new round knife. The version 2 is not very suitable for different sizes of knifes and the new one simply did not fit.
Therefore I came up with a new idea which incorporates the best of the two previews versions.
Pros
I was playing around with the dimensions while I was building it so everything is cut very rough. Also I have no propper workbench for woodworking and only very limited tools.

Pros
- Knife blade securely held in place without the possibility for any unwanted movement
- Pivot point in center of blade
- small overall size
Cons:
- A bit cumbersome to shift grinding/honing from one side to another.
- only short strokes with the sandpaper is possible.
- Each knife needs its own platform.
