No the other guy did it with u2, I used my spyderco centofante 3. It was reprofiled to 30° (factory was a bit more than that) and sharpened on spyderco sharpmaker and 1500 grit sandpaper. Hair is from my head.
VG10 actualy hold 30° quite well. But I do sharpening my SAK etc at 40°. My personal rule is that anything above 154cm is done at 30 while anything below is 40.
