I don't really like the design of this knife for a survival blade. For the price, you can't complain, but I would suggest the Schrade's SCHF37 Frontier knife; it's about the same price, longer blade, coated 1095 steel, no-serrations, and better sheath.
For $30, you get a lot knife with SCHF31S, but Schrade has better offerings for about the same price.
