Chisel bevel angles

**snafuspyramid** · 3rd August 2011, 07:51 PM

I've got hold of a bunch of Narex chisels (or will shortly) and a relatively complete set of Titan registered firmers.

I don't have any mortise chisels, except for one 1/4" Titan.

I was planning to grind the Narex to 25 degrees (they come pre-ground to this angle). Using the microbevel feature from my Mk II honing guide, I'll end up with a cutting edge of about 26-27 degrees. I want to use these chisels for paring and lighter work.

For heavier work and mortising, I was planning to grind the Titans to 30 degrees, which would result in a 31-32 degree microbevel.

Would these bevel angles serve me well for most things - from paring to mortising? Ideally I'd have dedicated paring or mortising chisels, but that's beyond budget for now. Or is there a better way of doing things?

I'm working with Aussie hardwoods.

Hi Eddie,

I'm in the process of sharpening my new Narex chisels and a whole bucket full of Titans.
I normally freehand my chisels or use an Eclipse guide, but those angles are what I'm aiming for. If you are likely to really bash your Titans you could go even steeper.
I've ground my bevel edge Titans at < 25 and honed at 25. They seem tough enough to handle that but I haven't tried them yet. I'll do my Berg's the same so I can compare them.
By the way Titan didn't call any of their chisels Mortice Chisels, only Registered Firmer Chisels (Plain Edge).

Best Wishes
Steve

Whatever they called it, it's a good deal thicker than the others - from front to back, that is. I don't think I'll bother looking for mortise chisels in the larger sizes (this one is 1/2") since the regular Titans are so solid, I can't imagine mortises being an issue.

I still have an Eclipse guide, but it isn't great for some narrower chisels. Mind you, neither is the MK II, but once I bought it I couldn't bring myself to part with it...

I might try the grinding at less than 25 degrees, to achieve a 25 degree microbevel, as you suggested.

Cheers,

Eddie

snafuspyramid:

For the range of (soft) conifer woods that I carve, I sharpen my tools to 20 degrees.
Knots are like bones in meat = my small "knot-busters" are carpenters chisels at 30 degrees for the smaller knots. I have one old chisel. 25mm/1" at 40 degrees, like a bone cleaver. I am pleased with the durability of those chisels & edge angles.
