Thread: Chamfering CFs

I have some CFs and a (likely) LI that need chamfering. Is my Atoma 400 is a good bet for this? Or should I use something else?

Normally should be no issue to do so. I always use a coarser DMT then i proceed to use SIC paper up to 800/1000 and round and smooth out the edges again.....

I had no issue just using my DMT 325

But then again I don't take Chamfering quite to the extreme I have seen out there in Razorland

You just need to knock off the very edge and make sure there are no chips / nicks on it, I have seen some 1/4" 45° angles cut into very valuable hones

I use DMT extra coarse 220 for this Well it isnt 220 long ago anymore but still ....

The atoma will perform just fine. They are the toughest diamond plates after all. Especially if it's a new one. I have flattened/made slurry on my sigma 1.2k for some 500 times, probably more, aside from other stones, and the plate seems to be at its limit, but that sigma stone is a category on its own, it eats diamond plates, not the other way around.
You'll have no problem, go ahead.

Why do you guys chamfer, its just extra work?

I think it helps, especially when trying to be very precise on the heel. I've noticed the more chamfered my stone is, the less likely I am to accidentally hone into the stabilizer. The 10 extra seconds it takes while lapping doesn't seem to be a lot of extra work.

If feels awkward when you hold the stone and the edges are sharp, I prefer smoother corners/edges than sharp ones on stones. Other than that... I guess, there is a small chance you'll mess up the angle of your blade and dig into the sharp corner of the stone, damaging the edge.

Must be holding that stone in a death grip! LOL if it is cutting into your hand.

I do have some maruka, Schwedenstein, huge Thuringians, WOAs etc stones that I do I hold with a "death grip" because I'm afraid I'll drop them, but they don't cut my hand. Still, it does feel awkward to feel the sharp edges of stones on your hands. A tiny bit of chamfering helps.
