Like this quote from Dumbledore, when he looks in the mirror that shows your deepest desire:

"What do you see when you look in the mirror?"

"I? I see myself holding a pair of thick, woolen socks."

"One can never have enough socks. Another Christmas has come and gone and I didn't get a single pair. People will insist on giving me books."

The older I get, the more I appreciate receiving nice socks as gifts.

I just buy 20 pack (or more) of black ones every few years.

My wife chuckles because I darn my socks a few times before throwing them out. I chuck them when they either aren't comfortable, look terrible, or are too damaged to fix.

I'm curious what tools and supplies you use to do it (besides the obvious needle and thread).

That's it- just needle, thread, and scissors.

I'd like to call out what a life hack merino wool socks are. Cheap cotton socks smell after a few hours, merino wool socks smell after a few days and last forever. Also if you get a decent pair, they don't itch at all. Amazon sells some cheaper 6 packs for $20 that will for sure change your mind on socks.
