not really 'equipment'... but oh well

where is your worst golf-related callus

there is this weird bump, more than a normal callus,  on my right (play golf right handed)  hand ring finger, on the distal side of the 1st knuckle,  basicalyl right above where the fingers of the hands overlap in the grip.  i hereby call it  'super callus'

I use an interlocking grip and have matching calluses on the insides of my left index finger and right pinky.

When I first started playing, I used to have massive calluses on my left hand at the base of my 3rd, 4th, and 5th fingers, and I would go through gloves like crazy.

I don't have those anymore, which means I must be doing something right.  Although I now have a small callous in a weird spot on my right hand these days. (right hand, midway between center of palm and base of 3rd finger)

It figures that you stand on the wrong side of the ball.
