Sharpening angle on BM 722?

[Colog]

Does anyone know if this blade is sharpened at a 20/20 angle from the factory? I want to use my sharpmaker on it.

Production blades do not have exact angles, they will vary from knife to knife and even from one side to another and even along the edge on the same knife. The only way to know is to check it on the Sharpmaker or just measure it directly.

I suspect Mr. Stamp was indicating that you should just reprofile it to the Sharpmaker's established angles if you wish to have 20/20 angles.

But, that's just interpretation and may (probably is) wrong.

You can use the Sharpmaker to sharpen it. To see how much reprofiling may be required (if any), just run a black marker along the cutting edge, use the Sharpmaker for a couple of strokes, and see how much of the marker comes off.

Keep at it till all the marker comes off when sharpening.
