Turning a Double to a Single Bevel edge.

[cmgray]

Hey how is everyone doing? I have taken on the tough task of turning a double bevel edge to a single. Anyone ever done this before. Im using waterstones and plan to start with a 200 and work my way up to a 1600. Any advice?

If, by "single" bevel, you mean chisel grind (one side flat, one side beveled) then patience, patience, patience. You will have to grind away all the steel between the right side and left side bevels (that's the entire v that forms the edge) plus grind away the steel to form the new single bevel. That's a lot of blade and stone down the drain. This is a job for a belt grinder. If you have the patience to do it by hand, get a cheap, very coarse caborundum stone and sacrafice it for initial grinding. Save your water stone for sharpening.

Just referring to a single change in angle from the spine to the edge, like a Kellman. I want to use the knife for more bushcraft tasks and find a single bevel easier to maintain and sharpen. Thanks for the tip on the stone. I will try that. I'm about two hours into and almost have it complete.

I imagine you'll be removing a lot of steel. If this is the case, I'd use something much more coarse and aggressive. I'd use the coarsest diamond stone or a power tool such as a belt sander. Careful not to overheat the steel if using power tools.

I actually do something very similar with many of my pocket knives that have a full grind, such as Case, Victorinox, etc. I use a belt sander. Carefully hold each side of the blade flat against the belt so that the blade eventually tapers to a zero edge, and then hone a micro bevel. This turns just about any blade into a razor. This method generally produces a full convex grind, very similar to what you might see on an Opinel blade.

Any advice?

Buy a scandi that already has a single bevel. A cheap one can be had for $10, and the sky is the limit for how nice and how expensive you want to go.

That is a lot of work to do by hand, and you are likely to quit before you ever finish.
