I’ve written before about Jeff Peachy, book binder and conservator. Though book binders do little woodworking, they often use woodworking tools to ply their craft, sometimes in more demanding ways than woodworking presents. So I found his Ten Commandments of Sharpening something I should share. I’ll paste the basics here but he elaborates on his blog (worth reading in entirety):
1. Thou shalt not round the bevel or the back.
2. Thou shalt not use jigs.
3. Thou shall look at the scratch patterns in the metal.
4. Thou shall use a bevel angle appropriate for the knife and task.
5. Thou shalt not covet thy neighbors knife.
6. Thou shall sharpen side to side.
7. Thou shall use a grit progression and entire surface of the stone.
8. Thou shalt not let thy sharpening system become glazed over.
9. Thou shalt not advance to the next grit until the burr develops.
10. Thou shalt not insult thy neighbor by insisting on the absolute superiority of any technique or system.
