My ideal duck hunting knife would be one with a heavy 4 inch to 5 inch blade (something you can whack a small tree limb if you need to clean a wad or mud out of barrel). It would also have slot and phillips screwdriver, bottle opener and a punch blade ( like an awl) which would be something you could use to punch out your trigger pins or pry a hull out of your barrell. The type handle would not matter to me.
