Chisel Backs

    I spent a good hour trying to get a polish on my chisel backs.  Still original grinding marks.  Using 1000 side of my Trend diamond plate.  Drop to 330 side?  Help, please.

    You could certainly drop to the 300 side of the TDP, but before doing that, I would step up to your next grit and see if the marks you are seeing are in fact 1000 grit and are now being polished out by the next grit (6000 in my case for example).

    I rotate back and forth. 30-45 secs on the 1k and 30-45 secs on my 8k, this makes it much easier for me for see the hash marks, also, make really really sure that you are applying even pressure all the way across the chisel.

    Thank you both.  I will try both suggestions (and, by the way, it is 300, not 330 as I said).

    I spent a lot of time with the Trend 1000 grit side and it just seemed to take forever. I decided to try a water stone, so I bought a 220/1000 Norton wet stone and use the 1000 side of that. It takes MUCH less time to get rid of the from-new grinding marks with the wet stone. I use the Trend stone for sharpening, and the Norton for flattening.

    I feel like every time I try to flatten the backs of my chisels I'm in my shop for hours and have very little to show for it. I finally got my 1/2" flat on the back and while I was using it the other day I sliced my fingers in several spots where the bevel meets the back. Are we supposed to break that edge of the chisel on those two edges or keep them sharp so we can use the sides as well as the cutting edge? This is the second time I've had this happen to me, and I don't know if it's just an idiot user and bad technique, or I missed a step in the sharpening process that eliminates this problem.

    I use to do the same thing. I thought I had weak girly fingers. What I do now is, after the back is flat. I set the chisel on its back on the 8k stone, and while pulling it flat towards me I twist. I do this about 3 to 5 times. It seems to break that sharp edge just enough to where it does cut me, but still provides a crisp edge for me.
