Putty knife and a sonic knuckle duster. The putty knife is inspired from a book I read, it's a blunt rod of metal/carbon fibre slightly resembling a knife, at the press of a button the top third heats up to the temperature of a star, glowing blindingly bright. It has a directional force field to prevent convection from burning me, but it cuts through object through heat alone. I have to wear dark goggles for the light. The sonic knuckle duster looks a little like a normal knuckle duster but releases a huge concussive force when I hit someone that send thems flying.
