Has anyone tried to sharpenthis way?

Hi,

Hows this for an idea; I've noticed that in the discussion of sharpening, people seem to think that you must have either good push-cutting ability, OR good slicing ability, not both. They also tend to refer to either corsely ground edges, or finely honed ones.

Has anyone tried grinding an edge with a coarse stone, then skipping immidiately to an 8000 grit, or just stropping it up real good? In theory, this might leave an uneven, microserrated edge with a razor polish, which would, also in theory, push cut as well as slice.

I'll try it if nobody else has.

I'm sure some have, if not always intentionally. If I go in haste from coarse to extra-fine, without taking enough time between, that's the effect. Right now, I don't have any belts between 220 and 800 for my 2x48 belt grinder, so I'm probably doing it without meaning to.

Remember, those "micro-serrations" may be handy for some things, but they aren't the same as intentional serrations that are sharpened inside the curves.

Have fun experimenting. I am reminded of a Bo'sun I knew who served on tankers. He sharpened his knife with a crosscut (not mill bastard) file, so he'd have a slight "sawtooth" effect for cutting large poly lines.

I mount the polishing tape blank on my Edge Pro, attach a piece of 100-grit sandpaper and put a really coarse edge on it. Then I go to lighter and lighter strokes with the sandpaper and over lightly with something a little finer to smooth it out just a little. Then I raise the angle by 5-degrees and use a polishing tape.

I have heard of this too, there is definitely a following in this area especially with those folks that use their folders for heavy utility chores. The scenario I have heard of is the oppisite though. Polishing the blade with a fine stone then using a course stone to give the "microserration" effect.

If you contact your local knifemakers supply they should have at least one book on knifesharpening ( I can't remember the name or author). You might also try posting this topic in the knifemakers forum here at BF. If you figure out a good method that gets results, let us know.
