Paper Wheels

[kwakster]

Currently busy with the same mod of another Gerber Applegate-Fairbairn folder like i showed earlier a few pages back.
This is how the knife looked when i received it from the owner, still with a single edge & an edge angle between 40 and 45 degrees inclusive.





And this is how the knife looks after grinding the new edge on the back of the blade & trying to match it with the reprofiled edge on the other side.
The scratch pattern complete with burr remains still present on the apex comes from a Rubber Wheel coated with ~ 170 grit diamond powder & wax.






The idea was to make the 2 edges / 4 bevels as visually similar in width & curvature as i could, with a specific edge angle of ~ 35 degrees inclusive, without damaging the names on the blade, and to create a new point that would be centered as much as possible.
Trying to achieve all these things at the same time freehand, together with many visual checks with a Victorinox loupe in between passes isn't easy, so i took my time.

Below you can see the end result after refining the initial edges with a Paper Wheel coated with 15 micron diamond compound & deburring with a second Paper Wheel coated with 0.25 diamond compound.
Both edges are treetopping sharp.










This is how Applegate intended the knife to be, a true folding dagger.
It can still be carried in your pocket, but the top edge is only about 2-3 millimeters inside the handle, so when deliberately trying i can just feel the apex with my index finger.

Now the thumb lugs stop on the grooved linerlock tab, so it would be easy to use a file or a Dremel on it's surface to lower the blade a tiny bit deeper inside the handle for added safety, as there is some room for it.
