If you want a psk sized sharpener use sand paper. 600 to 1000 grit wet or dry (the black sand paper) does a decent job on most edges. It is not as durable as other sharpeners but it is cheap and disposable. Just place the paper on a flat surface and use it like a stone. It might even work well placed on the topside of your tin with carpet tape, although i haven't tried it for that application. I have used it taped to glass for sharpening and decking edges on chisels and plane irons.

There are longer blades- box-cutter replacement blades. Even though you can improvise a handle by wrapping tape around them, it is one of the more foolhardy things I've seen done in years. And they are designed to snap, so maybe not.<br><br>And they can be stroped on glass, with the top of a car door window being about the best I've found. <br><br>If you pack a pencil stub in your PSK, then a handle is easy to make for a razor blade, and the curved ones that are more like a surgical scalpel have more cutting edge than those that are stamped on diagnal.

Thanks guys for the suggestions. I should of told you exactly what I've tried thou. Exacto ducted taped to pencil OK for gutting ect.. Razor blade on split stick bound three point with safty wire, thats what the two notches and hole are for right, OK reminds me of a flake knife but now I can snap the blade. Carpet knife blade modified with lashing cut outs, same size as a razor blade but now hafts alot better and strong enough to cut small game trap notches ect. I can live with that as a plan "C" but if their's anything better out there thats just a little better I'd love to here it. I'm a little long in the tooth and my back does'nt like carrying as much as some people do. Never needed more than two knives and I take alot less risks now.

Good idea! I have some 1500 grit paper.....I will have to try that!!!
