Thanks! I am particularly interested on the hook grip calluses on thumbs, I’ll look into that.
Calluses at the base of the finger (say, the knuckle-joint of the palm) are in my experience very difficult to classify. I get them there by climbing as you said, and though I also get some calluses on my fingers those tend to be less persistent and probably disappear most of the time (after climbing for awhile at my level of intensity I stop getting calluses). I have also seen them from biking—when I started out I used to look at people’s palms a lot and never came up with a reliable way to distinguish this from weightlifting. But if you could go into some more detail on the differences, perhaps I’ll add a more speculative entry and see how it stands up!
