DanaM:
radius I use oxy/acetylene torch to both anneal= soften the steel so it can be drilled/filed and then to reharden the blade. The only problem I see with the propane torch is keeping the whole blade at non-magnetic(red hot) you can't get one part red hot then another, the whole blade needs to be non magnetic at the time of the quench. Of course there are methods for just edge quenching.

radius:
hm...i don't understand why one torch would work and not another, unless the oxy torch simply emitted a way larger flame...i've seen videos of people forging knives...forging, not just shaping from flat stock...on youtube, by heating a railroad spike in an old barbecue filled with red hot coals...maybe i'll try that...

anyone here ever try that?

mullet:
 That is probally not charcoal but coal. It get's hotter. An OxyAcet torch gets way hotter than a Propane torch. You can turn steel into a puddle with an OA torch.

radius:
well, i have access to a propane torch but not the other, so i'll give it a whirl. 

i'm not after a puddle of steel anyway! ;)

i'm really looking forward to this.  I told some guys at work about the KITH over lunch on thursday, and they all think it's pretty cool...time to get to work...

good luck everybody

madcrow:
When I do the heat treating, I place the blade on the kitchen stove, turn the burner on high, and when it gets as hot as it will, I hit it with the propane torch until it is non magnetic.  Porpane won't do it alone, and neither will the stove, but together they will get it there in just a couple minutes.  One word of caution here, I have the stove with the older spiral burners that are made of metal.  I would not try it on one of the fancy new stoves with the glass top, or whatever it is.  You may be in for a big repair bill if it melts the top of the stove.
