Hi Guys
I'll bet in a 100 years, unless you've see or heard about it from that forum some how ..
you can't guess who said this..
Sorry, but I have to disagree with you on this one, from the experts
I've talk to on this matter, this IS NOT possible. Once the temper is destroyed
there is no plausible way to restore this. If there is, I wish you can share this
info as because as you know every knifemaker makes a mistake once in a while and
have to destroy batches of blades that have taken away precious time and materials

I'm not dissing him, but he does need more info than he's working with,
he is a Forman in a very popular knife shop..:o
 
Well I guess we will have to make sure our blade steel is not from recycled steel now. I just re-HT'd a 1080 hawk head and the file that now skates is just my imagination?
 
As stated above, with a permanent handle yes if not wishing to remove. Other than that an extra heat treat or two might be good anyhow. Most of us have had, a time or two, to redo the heat treat. (maybe I've had to more than just a time or two but I ain't telling.)

haha this was concerning a knife that went through a fire
not a problem.
handle gone,
the fire was just enough to kill the stag and melt the Silver solder from the guard, the blade was still hard but the question was if the blade got a bit hotter than the original temper heat and the Rockwell was now lower now

he said as quoted

Yes.. yes.. I do agree with him. :D

You cannot correct the destroyed temper with another temper.
What you need to do 's just put it on fire. And re-create a new temper with a desired mechanical properties. :)

It should not be difficult for a capable HTer. :rolleyes:
 
yes as far as im concerned, there is no un-temper method, without annealing or re-heat treating.
 
Did you folks know that mozzarella cheese is made from buffalo milk?

I am sorry I have a busy but very enjoyable weekend, and I have never worked with a blade that endured a structure fire. However I am a firefighter so perhaps it is something I should think about for the future.
 
Kevin,
Glad to hear you are doing well. Hope you get to ride your bike before it gets too cold and nasty.
Thanks,
Del

I'd be interested to see what you find out if you recover any burnt blades.

Yes indeed, may back is better and I have been riding.

I do have a folder blade and assembly that I fished out of a campfire pit years ago, anything organic is burned off from it allowing me to get mechanism ideas from it, but the blade was so oxidized that I never considered doing anything with it.
 
a friend gave me a stainless kitchen knife that went through a house fire. anyone want to experiment with it? i'm not sure if it was in a hot enough area to take the temper out since i never tested the blade but it sure looks like it was hot enough.
 
Dan, I had several heat treated blades that went threw a fire a couple years ago. It wasn't so much the fire that was the problem it was that stinking water they used to put out the fire that wrecked the blades. This thing is hanging next to my fire extinguisher.

At this (TOP SECRET) junk dealer, i found on the third floor a 55 gallon drum FILLED, and I mean packed with civil war era swords, all with the wood burned off and bent up. There were maybe 3 or 4 out of 50 or 60 that were still straight. A couple things you'll NEVER beleive too, there were a couple signed tang japanese blades in there too. Never did get a chance to get a rubbing, didn't even know to at the time.
 
And it's the bufala that gives milk not the bufalo !!! If you want expensive cheese , someone in Sweden is making cheese from moose milk !
