So I was wondering I know of a decent production style sword in 1045 or 1060 but they are through hardened. Would I be able to draw the spine back a bit with a propane torch without wrecking the finish? Just a thought because they are hardened to about 56-58
 
I would leave it alone. I'd be surprised if it is actually 58 Rc. (It shouldn't be anyway.)
If you simply heat the spine with a propane torch you'll wreck the piece for sure.
 
Discoloration is the least of your problems. You could just polish that off.

You'd have a very hard time controlling heat. You would not have an even effect and even if it was done perfectly, the benefits are subject for debate.
The proper non-differential HT will result in a very formidable sword.
 
Viking....was it a Viking style sword? are you looking to get a nice hamon line?
and where in Minnesota do you live?
You may be close ....
 
Its a katana, I may be wrong on the rockwell, but my thinking was soaking 2/3 of the blade width in ice water to try and keep from impacting the cutting edges temper. I know you can do this on a knife when heat treating but just curious since this is much larger...and has already has a good finish. I havent purchased the sword but thinking about it, but I want a more traditional softer spine...I am sure it was just through hardened to keep cost down. Alan...I am in the Cambridge area
 
For what it's worth, my advice is to buy precisely what you want and don't mess with a cheap sword. It's better to have a few very nice things than a boatload of junk.
 
Umm,,,,did you spend any real cash on this?....
I would hate to give you a bad idea that screws up a kat that you had some money invested in...
 
bare in mind I haven purchased the sword yet, it isnt a like a paul chen golden oriole or anything spendy....just a cheness sword but from what I have read a step up over like a hanwei pratical plus. Just a passing thought
 
OH,,,in that case.....well....getting a sword that you know going into it that it has built-in problems that you are tempted to fix yourself.....

Hmmmm.....I dont know...

It just seems like that sword is made to fill a different need...
You seem to want a more"real" sword...

Thus you may have to look at getting a more real sword to start with.
If you only what a sword to hang on the wall and look nice, then any sword will do...But the moment you start to think about doing your onw heat-treatments this is a sign to me that you "expect more" from the sword,,,You clearly are just not going to be happy with junk..

before you get a sword that you have to fix right off the bat...Lets look around just a bit more,...Perhaps there is a sword that will fill your needs, has a reall hamon from a real Heat-treatment, and is cheap enough for the pocketbook too....
