For a basic tool kit to start out with I’d go for the following:
12” Steel rule.
Stanley Knife or craft knife,
5 or 6 stitch/inch over stitch wheel,
Adjustable stitch groover,
Free hand stitch groover,
No. 2 edge beveller.
Awl,
Size 2 saddlers/harness needles.
Beeswax block
Thread
Pliers (useful for pulling needles through)
Hole punches (not the rotary plier type)
You don’t need all fancy kit to start out with you gather it as you go along. I use tools that I’ve got from Leprevo or Ebay and even made some myself.
Awls for example (not the diamond shape ones) I make out of large gauge darning needles, I’ve made edge bevellers out or screw drivers, grooving tools and even made hole punches
Here’s my main tool kit I use for most jobs………
(Sorry about the poor photo only had my phone with me
).
I have a separate sewing kit in a small tin, it contains needles, small SAK with scissors, a few brass poppers and tools and some thread.
Dyes, edge coat, fittings etc’ are all stuff that you experiment with to see what gives you the best results. But beware I've bought stuff on Ebay before and it's not quite what you expect ie: nasty smelling stiff leather and Brass D rings that go rusts:yikes:
