How many of you reading this have old wrenches not being used? My work bench is cluttered with wrenches that I no longer have a need for.
What I do have a need for, though, is more knives. Quality knives can be expensive to buy. What if you could make your own? It is possible, and all you need is an old wrench and a little know-how. It might not be the high-quality piece you might expect from name-brand knife makers, but it would be good enough to do most tasks that require a knife.
