I would suggest looking at basic tools to begin with, drawknife, spoke shave, round and flat bottom plane, decent moveable vice, solid bench. However it's each to their own. I picked up a really small cheap plane on Ebay, but find it great to handle the more delicate edges and toe areas, so it's about finding out what works for you. You can also make a basic set up for binding the handle using a drill and some wood.
Stickers can be expensive, so worth thinking about your design and how you many you're looking for originally. I got put onto someone in India and although greater MOQs, the cost per set was much cheaper than Adcal.
If you're talking clefts then you'll need saws, jigs for splices/handles, a bat press etc. All of which require greater knowledge/skill/experionce and money. If you're looking for part mades, there's a few places you can source these.
Good luck!
