SLOC is an acronym for Self Lubricating Open Comb. The RazoRock SLOC is based on a 1940's vintage razor called the Grand Shave King Self Lubricating razor. What makes the SLOC different is the open comb teeth on both the top cap and the base plate. The design helps to trap extra shaving lather in the teeth providing extra lubrication and glide on each stroke of the razor. Some people even call it the ultimate blade buffing razor because you can go over the same spot several times with less chance of irritation. The RazoRock SLOC uses any standard double-edge (DE) razor blades.
