I've got a metal detector and when I hunt parks I need a knife to cut through grass and into dirt. Probably want something with a serrated edge, and strong enough to take some prying, and maybe even some pounding into dirt. Something that I can basically beat the crap out of and store away dirty on occassion.
Fixed blade, around or at least 5" in length. Oh, keep it under $50.
I've been looking at Kabar, Camillus, and Ontario survival, military, pilot type knives.
What's your opinion?
