I see this question come up quite a bit, so I am just going to post this here. There are many very good quality "do-it-all" tool kits available that have bits for this knife, any of the GT's, and just about anything else you will run across. It makes it a lot easier to keep track of everything and you don't have to try to work with tiny, cheap, tools that slip off, scratch scales and are generally a nightmare to work with.
This set is a little expensive, but I bought it about 2 years ago and haven't had do buy anything extra since then.

Just putting it out there because I didn't know it existed until someone told me. Cheers!
Well allow me to share. I got alot of these as recommendations from Nick Shabazz https://youtube.com/@NickShabazz - a popular youtuber in the EDC community. Here is some of the stuff I use:
I happen to have these laying around but I use this to wipe with ISO alcohol and for removing wax
Renaissance Wax Polish is like wax on a car - provides a layer to protect and keep looking pretty
For wiping with the frog lube and wax
Polishing cloth for removing the frog lube
In addition to this, you'll need tools to disassemble the knife. I tried being frugal and so I bought an iFixit kit and a kit with Wiha bits. Good knives only ever use torx so this is what I bought
iFixit kit - The problem with this kit is the smaller driver is actually better in my hand. The Wiha bits are meant to fit the bigger driver. So the small is called a 4mm driver and the large is a 1/4" driver. I suggest finding a better 1/4" driver, Wiha happens to sell some nice kits. I'm just sharing what I got for myself.
I went through a few different sets - all pretty much crap. My advice if you are looking for a quality/precision set of drivers/bits is to hit up Amazon and just get this iFixit Manta Driver Kit: https://www.amazon.com/gp/product/B07BMM74FD
It is very high quality and I've been really happy with mine. I'm finally done looking for a quality set of precision screwdriver/bits. Mind you this is more for tinkering/tech/electronics applications though. If you want larger/heavier duty bits and larger screwdrivers, just hit up your local Home Depot or Lowes - especially over holidays when they have big sales. Most of the stuff on Aliexpress is crap and really crappy steel. The good stuff (name brands) with good steel/quality will cost pretty much the same as what you can get locally.
