Chamfer Advice

I have recently acquired a set of hones from the classifieds. Luckily these hones came flat, but the edges and corners are sharp and I would like to chamfer the edges.

I've found a lot on how to lap a hone, but not much on how to chamfer. Is this best accomplished with sandpaper, another hone, something else like a metal file? Is this best done by running the abrasive along the length of the edge, running the abrasive back and forth across the edge, or something else entirely? What about the corners?

For what it's worth, the hones are the spyderco set - medium, fine, ultra-fine. I understand that they are miserable to lap because they are so hard, so that may be a consideration for chamfering as well. Thanks for the help!

slap some sand paper on a flat surface. Run the edges of the stone a few times back and forth along the edge not perpendicular and you are done.
I do not chamfer the corners.

if you read how to lap just roll the edges of the hone on the lapping plate
(if you dont have a lapping surface yet its not nessesary with that much presition to round the edges)
wetdry sandpaper on a flat surface should work

All I do to chamfer the edges of my hones is just round them off with the DMT 325, but you can also use sandpaper.

Check this article from the Wiki as well:

This runs through both the sandpaper and the DMT method.

I've not got the Spyderco hones, so I dont know what they are like to lap or if they require any special treatment. Hopefully someone who has these hones will step in!

Good luck!

Sometimes with softer waterstones I've had problems from rubbing the edges back-and-forth upon the DMT D8C I use to chamfer, in that it ended up raising the surface of the honing plane nearest to those edges.

So now I move the hone's edge on the lapping surface only in the direction which keeps all abraded material away from the center of the hone, just a half dozen or so movements like that with the D8C on each side and it has no edges sharp enough to cause trouble.

I prefer to round the corners. Chamfers create 2 sharp points instead of one. Only downside to round corners is you lose water/slurry quicker.

ive used a sanding block and various grades to lap with cheep and very easy to use. You can pick up the lot, with various grades, for about £12 :)
