Reprofiling

[Robert Ptacel]

When reprofiling a knife on a coarse stone should you remove the bur on the coarse hone before moving to your finishing stone?

You don't necessarily have to remove all of it with the coarse, but you can (if you wish) use a few passes on it at much, much lighter pressure and slightly elevated angle to begin the removal of it. If you're confident in your 'light touch', much of the burr cleanup can be done this way. Otherwise, it's usually easier to start removing the burr with subsequent hones. Their finer grit will be a little more forgiving, if an errant pass or two is made (too heavy, wrong angle). A coarse hone can erase a burr, and the 'good edge' behind it, in one pass, if not careful.

Haa, no need to recount your experience with it. I believe you. Not that I've EVER done it! But guess it could happen... DM

I should elaborate that the coarse is used to thin the edge and then I put a microbevel on at a higher angle.When I was done grinding and got a bur on the coarse I raised to my finishing angle and took off the bur so my finishing stone didn't have so much to do.

I'm no expert, but I don't bother with the burr at all when thinning. I've tried a bunch of different variations on burr removal, but the one I like the most (currently) is the one bluntcut wrote about where you fold the wire edge over to one side by drawing the edge against wood and then cut it off with light edge-leading strokes on the stone (and repeat). I do that on the #5000(JIS) stone (or #1000, if I stop there). Before that, I just leave the burr and let it get cut off by the next stone or do a few light strokes (while keeping the same angle), alternating sides.

It only matters if you are finishing with that stone.

With each stone progression you make a new burr anyways so removing the burr on each stone before the final stone is not necessary.

Thanks everyone for your input.
