The curved edge on the karambit is tricky to sharpen.
No editing in the video so you see things real time.
This is a generic Sharpmaker system.
I should have stopped around the 2/3rd mark but tried to make it a little bit sharper and it backfired.

It can only go up to that certain sharpness, and it leaves a coarse cut on the paper. Best guess is a 5Cr13MoV.
