For a buttstock? Not much at all. I always recommend just buying one of those $30-$50 amazon beginner kits. The tools are far from perfect, but you don't know that, nor would you know exactly why an expensive tool is better. Once you want something more out of this or that, then you upgrade. You will also want to buy a cutting tool. Some use xacto knives, some use box cutters. Choose something and also buy a rotary cutter if you can. It makes long straight cuts a breeze.
There are tons of vids on buttstocks. To do it right, all you need to learn is the baseball stitch. There's a fancy name for it. It's the way you make a wrap for anything.
For bags and stuff, Chuck Dorsett with weaver leather is great. He covers so much.
I hope you love it, anon. Leatherwork is a great hobby. You will always give the best gifts
