I heard somewhere (probably here somewhere) that it matters which side the chisel grind is made on based on wether it is a left or right hand knife...if I wanted a right hand knife, which side to I leave flat? My guess is leave the left side flat, cause that's how my leatherman micra is....

and how do you sharpen these? work on the flat side and just work on the ground side enough to take the burr off and polish the edge, or the other way around, working on the beveled side?

For a right handed knife bevel the right side . Point of view would be with knife in your hand and pointed away from your body.

Sharpen from the beveled side only....

Chisel grinds cut away from the bevel. A left side bevel will tend to force the knife to the right.

A left side bevel will get in the road of whittling or slicing right handed so if you are right handed and want a working knife the bevel should be on the right.

Think of a wood chisel. The ground edge is always on top while cutting. If you turn it upside down, it changes the attack angle and the whole dynamic of cutting.

Take a look at an Opinel knife sometime. Few people realise it, but the blades are ground on one side only, for right handed users.

would I go and create that second bevel that goes down to the edge like you do on say a flat or hollow grind? my leatherman micra looks like it has a small enough bevel area that I can just match that angle......

from a second look, it appears that that micra is a flat grind combined with it sharpened on only one side....



on a side note, I broke a screwdriver on this micra as well as the scissors dont cut well anymore...anyone else have difficulties with it? I didnt pay too much for it, I suppose you get what you pay for...much better than the dime a dozen no name hardware store brands you see though...wonder if leatherman would replace it even though its been 4 years since the scissors stopped cutting. I'll have to look into that...

A chisel grind can be made by taking the main bevel all the way down to the edge. This is the way to get the sharpest edge but it's also the weakest edge and the most difficult to re-sharpen. You'll get a much stronger edge that is much easier to maintain if you use a secondary bevel....

Chris,

With respect to the Leatherman, I would give them a call. They Supposedly have a lifetime warrenty on them. Couldn't hurt to try, esp. with the broken driver (dull scissors probably won't get it though).
