Thompson skew *PIC*

>I finally had time to sharpen the thompson skew that I got. I was interested to see if it would get sharp enough to use as a skew. In the back of my mind I thought powdered metal might be like carbide and not get really sharp. Well I think I proved that wrong. I sharpened it like I do my HSS tools using diamond hones followed by green compound on a leather strop.

I established the initial grind using a 100 grit white wheel. That was a little slow but the metal cuts very well. I ground it 40 degrees from bevel to bevel and the tip angle is 30 degrees.

As you can see by the photo it is quite sharp. Certainly sharp enough to be used as a skew. I won't be able to use it until later this week but I think it's going to be a great skew. The rounded bottom should roll really well and the thickness should really help it cut cleanly especially if you have to hang it over the rest. I'll let you know what I think After I turn some spindles.
