I have a marking knife that really needs sharpening. And I’m not worth diddly-squat with freehand sharpening – seems I always round the bevel. I’ve read all about locking your wrists and twisting your body and dancing a jig while standing on your head and all that – didn’t do any good.

Anyone have any tips for this? I can’t for the life of me figure out how to make a jig to hold the angle on this short knife. It is a single edged knife, not a spear point which should make it easier, I suppose.

Any suggestions will be greatly appreciated!

Cut into your stone like shaving off a slice of cheese.

This knife will sharpen very much like a chisel. If you are not comfortable doing it freehand,which is an acquired skill from practice, then you should consider purchasing a sharpening jig for holding it at a consistent angle, such as the veritas.

It will be able to help you sharpen plane blades and chisels, as well. Sharpening is a necessary skill if you’re going to participate in woodworking. Tools purchased new are never sharp enough to do proper work.

I may not have any blade left before I get this thing sharpened!!! I have a couple of honing guides, including the Veritas Mk 2 (which is wonderful for plane blades and chisels) but don’t see any way the guides are going to help me with the marking knife. Oh well, guess I will just have to keep wearing away metal until I have something that resembles sharpness.

Maybe you could use an exacto kinfe and eliminate the problem?? Maybe it is bad steel??
