Can you sharpen the new negative rake scraper?

To me, it looks like you can't unless you can hold a stone at the right angle.

... and spin the tip while you hold it at that angle. (Or hold the bit steady while you go around it with the stone at the correct angle. Repeat for the other side of the tip.

If it is a carbide tip, then you would would probably want (need?) a diamond stone to sharpen it.

The short answer is no.

FYI, the discussions on the pen turning website reached the same conclusion. I sharpen regular carbide tips by flattening the backs on diamond stones. The problem with negative rake scrapers is that they don't have flat backs.

It looks like you and I are thinking along the same lines. I don't think I will be buying any of those cutters.

I would not hesitate to try. My first thought is using a small faucet washer and a screw, chucked in a drill to spin it slowly and use a 600 grit diamond paddle then 1200 grit if necessary to re turn the radius wanted. Use a sharpie to reveal your progress. I don't think it would be much harder than sharpening a carving tool that has a radius. Most router bits are sharpened to 600 grit. I say go for it!

I agree with you, Gary go for it. If the bit is dull you don't have much to lose.
