Chisel edge

Wed Nov 21, 2012 11:54 am

My brother came on down to NC for a visit and brought me his Emerson folder, which needed some serious TLC. I proudly broke out my Atoma and Nubatamas and went to town. It had been years since I sharpened an Emerson, which traditionally uses ATS-34 steel and features a single bevel, chisel grind. I laid down a sold bevel, progressed through my stones as usual, finished on my Jnat, which gave it an aggressive edge.

I often tend to strop off the non bevel/zero grind side of the chisel edge on each stone prior to progressing to the next, thus removing burr. I'm wondering what might generate better results, stropping on each stone, or waiting until the finishing stones and stropping less? Technique, technique, technique. - Josh

Don't start de-burring the back side until around 1k and even then only a stroke or two is all that's really needed. Beyond 1k the burr formation should naturally decrease with the finer grinding and with the final stone you should only need to make a few light passes at the very end to each side for complete burr removal. Emerson knives 154cm is not very hard @ 57-58 so burr removal will be a issue if you use lots of pressure throughout sharpening.

Better results? Try stopping at a coarser grit. bamboo 1200 is what I usually stop at on softer production knives.

I usually use less and less pressure as I move up the grit progression and then I switch to stropping on my final finishing stone and that seems to work for me pretty well.

You can strop a a few strokes on each stone as a means of abrading any burr you have and I sometimes do this instead of drawing it through my cube. I can't imagine you would get worse results by doing this. I think it's especially good if you section sharpen since a few stropping strokes tends to even out the edge.

Hey Jason, are you still in NY? How's it going???

As usual Jason, I can always count on your insight, I do appreciate it. Also, thanks for the correction, 154cm not ATS34. I'll give that strategy a shot. I'm still building my arsenal, got my 5K bamboo coming from Mark as we speak, the 3K is in my sights next, but now I'll need to consider that 1200, since I do find myself dealing with those popular pocket folder steels quite often.

Thanks for chiming in too Mark! I know you have the pleasure of experimenting on a regular basis with your inventory and providing feedback that can benefit all of us. I have indeed found better results stropping on my stones to remove burr than other mediums, felt, etc.

thanks again Gents!

The 1k is good too, little coarser than I like but more than enough refinement for a EDC.

Still in NY, hope to be home by x-mas.
