I'd like to jump in here. Nobody has really answered the original question. Which clipper clips to the shortest length.
I bring this up for a reason. Last night, I met some friends at a restaurant. A mom and dad, their daughter and her boyfriend. The boyfriend looked shaved bald ... but as I talked, he said, no, this was just clippers. I really want to shave bald or find a barber who will do a razor cut. Well, the barber across the street does them! So I gave the reference. (thank you, he said). I could not talk too long, but I was really curious, which clipper he's using to cut that close. With my wahl, when I clip to no guard, I don't look that short. Maybe I need to adjust the blades on my clipper. Maybe different clippers had different minimum lengths. I think this was the original question.
I'll agree with the current discussion ... why not just shave and be done with it. But along the way, or perhaps if your blades are all worn down and you want a very close buzz ... which clipper would do the best job? Which would be closest to sly?
I think that was the question. So, let's discuss.
