A friend recently asked me what kind of sheath knife he should get to $40 or less that would be a good general field blade and also be okay for field dressing game etc. He wants something with enough size and mass that it could be used to aid in shelter building in an extreme emergency but without too big and clunky to slice well and do finer work. Around a 5" blade. I have a few ideas but nothing sprang to mind as being "just the thing". What do you folks think? Marcus
