the blank goes all the way except for the last 1/2 in. (approx.)
about an inch up from the bulb, I've cracked the cork a few times. usually only about 1/2 way around the grip. this last Saturday I pulled off the whole bulb.
the last 3/4" of the grip. leaving 3/8" of blank exposed. akward casting that way!! i'll try to get a pic of the glue line.
