There is probably more but this should get you going - pick and choose ... from my brain dump....
- English Style Drawknife [well that is what I use - if they sell old one's the steel is better] be careful one fell on my hand the other day and it wasn't pretty
- Something to shape shoulders and handle if required [spokeshave / rasp / subform / careful use of draw knife]
- For Concaving - No 4 or No 5 Travisher or Convex Clifton spokeshave some pic's attached [or round bottom plane]
- Smoothing plane / I also use a little block plane and thumb plane
- Something to sharpen tools with
- Good vice & protective vice jaw [thingys]
- A good sturdy bench - when you start shaving with your draw knife the bench will move :-)
- Sanding solution [hand sanding / power sanding / how are you going to sand the concave without pneumatic sanding drums]
- Sandpaper various grades to suit solution
- Binding material [& possibly how you are going to do it, you can hand bind]
- Grips
- Some soft lead pencils if following lines [an eraser :-)]
- A few lint free cloths for oiling
