Hey folks...looking for some good, sage advice here...I currently have a BM Grippy 551S that I carry while hiking/backpacking, but I need to get something for my wife, in the case that she has to use a knife, and I'm unavailable for some reason (lost, pooping, eaten by bear, etc.)...I'd like to stay under $50, have a blade no less than 3", and have it be moderately reliable and sturdy...thanks!
