Thoughts on Stonewashing a Composite Blade Kershaw.

The thought popped into my head today about stonewashing a couple knives, I began looking through what I have to work with and found my CB Leek. Has anyone stonewashed one of these before? Or stonewashed any CB Kershaw? Any advise/pics would be appreciated.

I tried to etch my CB Rake, which has the same combo as the CB Leek. The CPM-D2 part only got a bit shinier while the 14c28N part developed some pitting. I didn't bother to tumble it because it didn't come out like I'd hoped.
 
D2 is brittle. The stonewashing process much chip your edge rather than just dull it. It's not a problem if you're good at re-profiling an edge. Could be quite a job though. It took me a good minute to re-profile a Sanvik edge. I guess I take my time. Still D2 would be trickier.
 
I have wondered this myself a few times I have a CB leek that's got some ugly scratches on it and was thinking a stone wash could potentially hide the imperfections
 
I actually had mine in the middle of the process as I posted the thread. I'll post my result pics. But I will day this, before the knife was washed it had scratched on the blade from someone scraping it on a stone, those are now gone.

How do you stonewash a blade? I have some scratches on an S30V Leek and my ZT 560. Does stonewashing void the warranty? Does it take off the logo and model numbers or do you tape over those? I don't suppose I can just put a jar with some rocks in the clothes dryer? It can't be that simple.

It is lol. Just take an empty jar (like a peanut butter jar) put some smooth stones of different sizes and some broken glass in it with all the metal parts you want to stone wash. Put some WD-40 in it as well. Put the cap on then wrap it in a towl and throw it in the dryer for an hour or two. :thumbup:
 
How much damage does it do to the edge? Would it be a good project before you reprofile a knife?
 
Oh yeahhhh, I owe you guys pics. It just dulled the edge, I was expecting the d2 to chip but it didn't. And I used very large rocks.
 
Do not put a jar of WD40 in the freaking dryer!!!
Thats the stupidest idea I've ever heard. Even if you have a no heat tumble, if it ruptures you'll make quite a mess. Shake it by hand or get a rock tumbler. I put a Scallion and Leek blade in a rock tumbler with a couple handfuls of stones and about a 1/2 cup of WD40, no glass! It dulled the blade pretty good but it was easily resharpened on the sharpmaker. I can't say how D2 will do. It did not remove the lettering but it did fade a tiny bit. They came out very nice. I'll post pics when I get home.
 
In the dryer I use a bit of dawn and water instead of WD40. I also have some rust stained towels now though lol. Good excuse for the wife to get a new set :D

Well, I wasn't actually going to use glass, and I'd suggest duct-taping a strong polymer jar closed and then duct taping an old towel around it, then throw it in the dryer with a bunch of other old rags and no heat. I'm thinking this wouldn't work with a DLC blade, though. It would take too long and the lettering probably would come off. One reason to avoid DLC blades.
