What im lookin for is some advice on a knife one can carry for the coast gaurd... the only real limitation is budget and blade length. The rules pertaining to carry on the ships is a 4 inch blade or less. The budget is 100 bucks. The knife isnt for me but a friend. What would be ideal is a knife with good edge retention because "she" isnt keen on upkeep.. which also means its got to be rugged. Excellent corrosion resistance is necessary due to always being near the ocean. Assist opening would be cool but not needed as a folder is deffinitly needed for concealment on ship. The knife needs to double for combat and edc use. Just wondering what your guys opions would be. All the while shes never had a nice knife and cool factor would be an added bonus! thanks for the input
