Survival knife sharpener

[CharlesHarris]

I agree that the industrial diamond sharpeners are best and easiest for most people to get good results with for field use.

I have the EZ lap rod and a 1"x3" pocket stone with fish hook groove in my kit, as well as a Pillar file for sharpening machetes, axes, etc.

Back home in the shop I have an assortment of Japanese water stones for fine work, and a Lansky sharpening kit and holding fixture with Diamond stones from 120 to 1000 for routine stuff.
