AgreedWorksharp field sharpener
So I just started using the "Block" sharpener. Block is the guy that makes it and not the shape. I had been looking for something a long time like a field version of the knife honing steels I use in the kitchen. Especially with infi, I rarely need to actually take metal off. Usually it's just a touch up or to straiten something. I was using small ceramic or diamond rods, but I think this thing is really good for me. I tend to steel my knives a lot, but rarely sharpen them.
I get old mousepads, cut them into 6 pieces and glue wet sand paper 600 - 1000 grit. Easy to carry and works for me. Dirt cheap to.
