Grinding down a DMT XXC?

[THG]

I've had this DMT XXC stone for a while now, and I don't use it because of the damn, stupid rounded corners. What do you guys think about grinding down the corners to make them sharper, and therefore usable? What would be the best tool to do this? What would I have to look out for (heat, burring one of the corners, etc.)?

Thanks.

What about chamfered corners is a problem? I've got several thousand dollars worth of stones and the only square edges I use are on tiny finger stones, for detail work on points and burrs and serrations, ie tight spots.

For cleaning/flattening other stones or rough stock removal grinding the chamfers hurt nothing. What's your issue?

You can't sharpen a knife whose edge meets the ricasso because the stone can't get in there. If I were to use it, I would lose 1/8-inch of cutting real estate or more.

You could take your DMT's to a machine shop, where they could grind the chamfers off with a big belt grinder.

Another way to get that tough to reach area would be to pick up a set of DMT files. They come in a pack of 3 grits with plastic handles.

It wouldnt be a massive undertaking one way or the other I don't think assuming you have access to a decent large belt sander or bench grinder. Nothing I have ever done before as it has never really been an issue for me

I sometimes grind the ricasso back to give better access to the working edge. I use a sichtschleifescheibe (slot wheel grinder). You can watch the wheel remove the excess material.

I'm not sure you could do that on a Spyderco lock back, for example, since that part of the ricasso is used as the kick to stop the blade in the closed position.

I understand your frustration but why not just correct when you move on to the XC? Its what I do. You could also look into getting a norton Sic stone....

Well if I do a whole reprofiling job on the XXC stone and then move onto the XC stone, I'll have a whole section with the old bevels still. That's like reprofiling twice...

An 1/8" of an inch!
