Gillette New versus New Improved - Do I have my data correct?? The New Improved was actually the predecessor to the New? There are News with short and long combs, yes? I can't seem to find a picture that makes the difference in tooth length clear. How do their shaves differ? Which three piece has the long TTO knob/key that is removable? The cap plate comes off, the key slides out of the handle and the blade bed, if that's what the bottom half of the head is called, stays attached to the handle. I'm not referring to the two piece like my Hoffritz Slant two piece. What is the back story to the name Bull Mastiff? I have one from Bob's Razor Works in the black anodized finish and I like the size of it.. What other razors use a similar handle or one that is called a Bull Mastiff?
