Sharpening a chisel grind?

[Raylas]

Okay, so I got a brand new, beautiful Boker Kiridashi in the mail today. I love this thing, and it's screaming sharp out of the box, but there's one tiny problem..... I don't know how to sharpen a chisel grind. I have a VAGUE idea of how to sharpen them, but no real info. So I thought I should come here for help, the best tool I have available to me is my sharpmaker and my homemade strop, how would I best go about sharpening my new kiridashi on these tools?

you need to work up a burr by working on the secondary bevel side and strop the flat back side which is where the burr will form. you never want to touch the flat side on a stone. you can use a piece of glass with some 400 grit wetordry sandpaper on it. match up the existing secondary bevel and push it away from you and keep making passes until you get a burr to form.

i make chisel grind knives and thats more or less the process i use except i use a belt sander or paper grit wheel to work up a burr and a slotted wheel to remove the burr. a chisel ground blade can get wicked sharp. http://www.youtube.com/watch?v=I7iDE2EBzBw

What's the piece of glass for?

you lay the sandpaper on the glass for a flat surface.

Oh okay, that makes sense. And thank you, it helps knowing I have somebody I can ask for help. I'll give it a try when the blade needs work, and it sounds like once I get it down it won't be so different from a regular knife.

i like to put half a convex edge on the chisel grind knives i make. the convex edge seems to be easier to maintain. the knife in the vid cutting the free hanging newspaper has a half convex edge.
