I'm surprised by this thread 'cos I thought the skin hardening thing would be as common knowledge there as it is here. Many a tenderfoot here gets the advice to toughen them up with spirit and have for as long as I can remember. I never thought of guitarists and oarsmen using it for that though.
Here's the thing. Skin hardening is not the same as skin toughening. The former is a result from rinsing out the oils in the skin. The latter comes from skin growth. Skin oil, among other things, is a protectant. Excessively removing skin oils also removes some of the ability for the skin to repair itself, the result being cracking and flaking.
Skin toughening, on the other hand comes by hard use, resulting in thick skin growth. Otherwise known as callusing.
The guitar fingertip idea illustrates to me why this really may not work as intended. Having played for a few decades now, there really isn't any alternative to toughening up fingers other than just playing the guitar. Drying out the skin on the fingertips makes the skin hard, but not tough. If anything, it makes the thin skin more prone to pain and damage, because of the loss of elasticity and moisture.
I did do a google search with the key words, and what came up seemed to be the same lore repeated over and over. Because of this, I'm not impressed by anecdotal reports of folks using IPA to toughen up feet. Evidence of the ritual is not evidence it actually does what it's supposed to do. The pore tightening action is exactly what astringent does. This is the practical use of aftershave, the main ingredient of which is typically alcohol. Some men use the stuff on their face every day with no significant skin toughening.
As far as the buy who claims his nutsack went leathery after application of IPA, I'd say after cutting himself and application of alcohol, his scrotum isn't exhibiting hardened skin. It's cowering in fear for the next stupid trick the guy is gonna try.
