Hey Bill
   I have done this --lots-- of times
That is a weed torch you showed. Certainly adequate but serious overkill.
2 ordinary household torches are totally sufficient unless you are doing 
something very large.
Any old oil you have an excess of will do fine. How about some of that 
22 gallon vat you bought at Costco? lol  Just keep a handy cover to 
smother the flames. A shingle or whatever is nearby.

      Here you go

  For a cutting tool, to temper it, you might want to just bake it in 
the oven alongside a pie.
350,  45 minutes, its perfect.
      yours Scott
