3 1/2 blade vs 4 blade

@swimma26 That's a good question...is 3 1/2 a people blade maybe? When I think of a 3 blade for grooming I think of the 3 3/4 (13 mm). Amazon reviews for the 3 1/2 show people using it for humans and dogs so honestly I don't know.

EDIT: NEVERMIND I FIGURED IT OUT!! So most andis blades will either have an AG or BG on the front of it. AG stands for Animal Grooming, BG is Body Grooming for barbers. So yeah, technically the 3 1/2 is a people blade. No difference in length from the 4, just not for animals.
