When I got the Puma, it clocked in at 3/8," so it's not all that much narrower now than it was. I can't say for certain what it's size was when it started its life, but based on how naturally the shoulder seems to blend into the heel, I'd guess it was either always a 3/8" or shortened by someone very, very dedicated to detail. The chip in the blade, when it came to me, was just off the point, so rather than hone down the entire thing, I tried to round the point gently into the length of the blade. All that said, I agree it probably isn't meant for shaving so much as shaping.

If anyone knows their Pumas well enough, and can attest to the widths of the various models, this one is stamped '44' on the shank.
