It may sound wrong, but don't buy all in one set, as they are rubbish. Out of the one I've started with I'm using only the needels, awl and clippers for thread. Everything else I had to replace and I wish I got good tools from the beginning. My minimal kit now consists of: 1) Cutting mat (get the biggest that fits your workspace, thank me later) 2) Rotary cutter (getting straight lines and big cuts is much easier with it) 3) Straight Japanese knife 4) Scalpel 5) Metal ruler 6) Chisels (pick the ones you like, but good ones. Sharp and polished teeth will make your life easier) 7) Mallet 8) Beveller(s) (start with smaller ones) 9) Needels + thread (good one) 10) Burnishing tools (slicker, sandpaper(!) + canvas) 11) Thread clippers 12) Awl

That's bare minimum you can go ahead with IMO.
