Hardening and tempering

(1/3) > >>

DC:
I was watching "Forged in Fire". They were all using the same steel. Some blades chipped and others folded. Since somebody other than the contestant tempers the blade(a sore point with me) could the tempering be causing the failures. Put another way if two people use the same steel and one hardens his blade at a higher temperature could different tempering methods make both blades survive?

KHalverson:
In my opinion yes.
There is just way too many variables between 3_4 different smiths to let 1 individual govern a temper .

burchett.donald:
Every steel has a recipe...So many variables...So many recipes...What steel were they using...

DC:
Sorry, I can't remember. I've only ever used truck springs and that was long ago. It's just always bothered me that we don't get to see or even hear about the tempering that's done on that show. A guy loses a chance on 10 grand because his blade chips. It may not even be his fault. I may be wrong on this because I only heard the "someone else is tempering" from one spot. I wish they would explain a bit.

bubby:
The mastersmith does the tempering on all blades. They know what steels they used and watched them forge them, it seems most of the chipping comes from to thin an edge profile most of the time. They also use a even heat oven to treat them and make sure of the temps.
