My wife is looking for a fixed blade knife for her "car broke down/bob". From her description it sounds like she would like a boning knife . She usually uses cheap knives and throws them away but now she wants a nice one. My question is do any of you all know of a good fixed blade, sturdy knife that she could use in an emergency that fits that profile? Would a high quality kitchen knife work? Can I get a sheath for a kitchen knife? Thanks in advance
