Not totally true. I worked with my hands for years and had pretty rough hands from it but I noticed my friend in an even rougher industry (HVAC) so I asked him wtf he was doing and within a couple weeks, my hands were on great shape.

The answer is using lotion AND preventative maintenance. If a callous starts to rip, smooth it out with an emery board. It's otherwise not that rough if you losh up 2-3 times a day

I think it's fair to say I work with my hands, what with setting tile. I don't let my hands get gross but lots of my coworkers do.

You might be able to handcuff them with a dry microfiber, but the cloth just slips off of my hands
