Well I have had this idea for a while now, and had some time to make a couple of prototypes.
The handle is .375 diameter 6AL4V Titanium, while the business end is .250 diameter micro grain carbide.
I have been saving my broken carbide end mills for some time now figuring I'd could come up with some use for them, so that's where the micro grain carbide was sourced.
I surface ground a flat onto the carbide, and then with my carbidizer added a layer to the flat to give the surface some texture.
Okay, while can't re profile your blade with it.
If you're out camping, and dull up your Jared Ryan Price friction folder slicing Lemons to garnish Margaritas on a hunk of firewood for all your friends you can resharpen it with this little hone.
Hope you like em,
