An Adventure Network surfer recently asked me the following: "Try as I might, I just can't seem to keep my pocket knife clean. It fills up with all kinds of gunk and crud and takes ages to try to scrub and pick all the dirt out. There has got to be a better way."

There is a better way:

Think hot water. Whether you own a Swiss Army type knife, a multitool, or a simple two blade folding knife, a pan of boiling water is all you need. Open up all the tools in your knife and drop it into the boiling water. Leave it to cook and clean for no more than a minute. Remove the pot from the stove, carefully pour out the hot water and then slowly add warm water (cold water might crack the plastic handles). After a minute or so, carefully remove the knife--it's probably still hot so using tongs is a good idea. Keep in mind that the plastic covers on the knife handle may have softened during the boiling process. Handle carefully until they have hardened completely again. Also, handle the knife very carefully when all the blades are out. This is the most common time for little nicks and cuts to occur. Remove all the softened crud that's still clinging to your knife with an old toothbrush. Finally, allow the knife to air-dry and then coat it lightly with a layer of cooking oil, rubbing off the excess with a paper towel.
