On my wood stove we have a Harbor Freight butane torch, currently one of the old orange ones with the knob on top that I'm sure isn't OSHA approved... anyway, the newer black ones aren't too bad either, but neither are the $5 generic "crack torches" from the gas station or grocery store checkout. They're all hit or miss, I have 4 of the old orange HFT torches, two still work, two leak. Heck, I even have a couple of the older black self igniting pencil torches floating around. I might be a pyro or just a collector of nifty stuff? hoarder? not sure, I'm trying to get better at accumulating...
