I've got a sharpening system for the house, but in the ever lasting quest to bug out light, I'd like to get a sharpening stone. Where do you get just the stone, the kind that would fit in the little pouch in a knife sheath?

Two places that I can think of - excluding internet purchasing:

Higher end knife shops - including hunting stores and such.

Higher end tool shops - here in the Chicago burbs we have a chain called Berland's House of Tools that has all sorts of great gear (GB axes, nice saws, LM knives, Streamlight, UK, and other nice flashlights, etc...).

I don't know if this is small enough for your needs (it's 4"X1"), but I have one of these Buck sharpeners and it works great. The price here isn't bad either.

Have you thought about this guy? I'm giving this some real thought about this for my BOB.

www.ragweedforge.com Ragnar has both diamond plates and a traditional viking stone in small sizes. The stones, besides beautifull ( who says survival has to be grim black epoxy or international orange <img src="/images/graemlins/grin.gif" alt="" />) do a very good job within their limits. The smalll two sided diamond plate lends itself to many ways of attachment. On my old Cold Steel SRK I slipped it underneath the paracord wrapped around the sheath. You might also consider a few sheets of wet/dry sandpaper in your PSK. Lee Valley tools sells superb sheets used for wood chisels.

I second the motion for wt/dry paper. I use 1/2 sheet 220, 600, and 800. I would get a few sheets at your local NAPA or other auto parts that sells auto paint and supplies. I order from Lee Valley and other woodworking supplies quite a bit, and if all you get is the sandpaper, you'll pay more in shipping than you need to.

That selection of grits I mentioned isn;t what you'd use at home, of course, just for use in the field if you had to dress up your edge. I've also recently began to carry a diamond rod sharpener that retracts into a pen-like tube and is no bigger than a writing pen...just in case I had to take some or all of a ding or two out. I think I picked it up at Lowes for about $9

The Double Sided Diafold® sharpener is what i carry in my bob. Works very well, i like the fine and course stones in one package.

Any cutlery store should have them, any sporting goods store, and Wallyworld type store in the sporting goods section, any hardware store (they usually have a portable glass fronted case with knife and some stones, many times located near the checkout). I have many diffrerent type so sharpening tools, for what you want I would suggest a diamond type of "stone," either a small flat one, or my latest carry tool, one of the long skinny types, flat on one side, the rest round, which stores in a case about the size of a ball point pen (I tried to find a pic to post and couldn't). Diamond is nice because you don't need oil, water, anything, to use it...

I have 2 of them, one sits beside one of the original LM in its nylon sheath. The other is with my V Swiss tool, Mag light, and Sharpie in an Nite Ize Mini Pock-Its case. It is made by EZ lap and the Scout Store has them. I need to think about getting a third to keep in mu Go bag

WoodCraft, or any tool/supplies store that services woodworkers. There is a wide variety of stones in many sizes and shapes.
