How to sharpen a chisel ground blade?

[KyleMS11]

I have a spyderco pancehnko dog tag i need to sharpen. Wondering how i am supposed to sharpen a chisel ground blade? Do i just sharpen one side? Ive heard it can be tricky. Is it possible to do this with a sharpmaker? Thats all i currently have. Thanks for any help.

Sharpen the bevel until a burr forms on the flat side, use a fine or UF SM rod to to remove this burr periodically. Try and be consistent on the back bevel, I would set the SM rod in the 15 slot.

Jason, would you suggest laying the flat side of the blade flat against the rod and then lifting the spine just a hair to knock the burr off? This is how I do it on my Lansky rod systems. Or...Would you just hold the blade vertical and knock the burr off at the same angle as the beveled side?

Thank you. Will give it a shot.

I'm not Jason. But that's the way I do it. Adding to what Jason said before: When sharpening a chisel ground blade, I like to minimize burr production on the "flat" side, by doing light strokes periodically on the flat side. Say you have a total of 10 minutes of work to do on the ground side with a coarse stone. In that case I'd do a short round of strokes on the flat side every 3 or 4 minutes. That way you never build up a giant burr to remove. Eventually you'll grind the entire beveled side correctly and end up with a small burr on the flat side.

I do this same thing with serrated blades, but it's in reverse since I do serrated blades from the flat side for most of the grinding and only knock the burr off on the beveled side of serrated blades. That's another lesson from Jason.

You don't have to be Jason. All opinions are welcome. Good advice, btw, on not developing a giant burr. I'll try that next time. Thanks. :thumbup:
