Thread: Honing Guide Protrusion Stop Angles

I made mine in 5º increments

25º - pairing chisels
30º - general purpose
35º - older tools with softer steels
45º - scraper plane blades
50º - bevel up planes

Thank you, yes I think I might go with that,
Can't really see any other useful angles

Kind regards

Did you not include 40 degrees?

Bench chisels and plane blades will hold an edge longer at 32 degrees.

Hey Derek,

Is this the primary bevel your talking about, or the secondary bevel?

You guys have done it lucky over there

It depends how you sharpen. I hollow grind at 32 degrees, then freehand on the hollow. In other words, that is the final angle.

If you use a secondary bevel, 32 degrees would be it. The primary could be anything less than that.

For planing - grind anywhere from 20-25

hone with a middle stone 32/33

Hone with an ultra fine stone 35

(for a bevel down plane with a cap iron bedded at 45).


What you lose in a little clearance, you'll gain in edge strength and lower damage plus some .

maintain geometry at 32/33 with the middle hone and just remove waste with the grinder at the low angle (if you don't have a grinder, then I guess a long run of coarse aluminum oxide for the low angle, but you have a fair chance of grinding camber without wanting to).

If you're using a bevel up plane, you're far better off solving the cap iron.

For chisels, grind 20-25, hone at 25, tiny strip then at 33/34 with a super fine abrasive (and I mean tiny - like a small fraction of a mm).

remove the tiny bevel each time you rehone.
