I'm not all that sure that most commercial sword companies even heat
treat, much less a custom technique like zone tempering. First, you'll
need a blade made from a shallow hardening alloy, and old truck springs
don't qualify, neither does old ship hull. Get out the Big checkbook.
There are makers that will fab to your spec, but they aren't cheap.
Well, i do have a sword hangging on my wall , a blacksmith i know forged the
blade out of a old truck spring.
I have asked i he could harden it, but he is too occupied making damascus
knife blades, so no luck there...
Due too the fact that i live in norway, and blacksmiths that has knowledge
of clay hardening are impossible to find, i do not know what too do.
And commercial hardening are way too expensive.

You think factory mass-production is too expensive, but you're looking
for someone with the rare skills to do this, then you expect them to
offer you a bargain price ? Have you _no_ respect ?
You don't deserve a sword. Learn to do it yourself.
I meant that moust factorys involved in hardening , use batches , or runs if
you understand. And the one piece costumer are charged a hefty prize.
And it is wery hard too find people that has knowledge of clay hardening in
I have great respect of blacksmiths.
And no respect for flamers.
Don't get upset, truck spring makes an excellent sword, but 5160 (which is what
most of the US rides on) is a deep-hardening steel, and doesn't really respond
all that well to the clay mask treatment. The whole point of the mask is to slow
the cooling of the areas under it during the quench. What you need is a plain
carbon steel with at least .60 % carbon to start, and a water tank to quench it
in. The mask is essentially casting slip used for poured ceramics, mixed up
thick and painted on. The thicker the layer, the slower the cooling. We're
talking fractions of a second here, but that's all it takes. Ideally, you end up
with a full hard edge, transitioning into a spring hard core, so when you draw
it you get a nearly full hard edge and a nearly normalised core. This gives you
edge retention backed up by toughness against shock impact. I tried it a bit
some years ago, it was more trouble than it was worth. When you add in the extra
materials, the prep, the time; it pushed the vend price above what the market
was willing to pay. And... it's a crapshoot. Heat treatment is a Dark Art still,
and absolute repeatability is still just out of reach. Even with computers, most
makers only guarantee to +/- 1 point of Rockwell, which is a 2 point tolerance.
Get out the Big wallet; you get what you pay for. Fast, Good Cheap; choose two.
A sword like that done by sombody who knows what they are doing would only
come from a custom maker and will cost you a thousand and up. For a a
decently made and treated for $400 and up you can try these folks:
I'm pretty sure they make swords you can beat the crap out of without
breaking and yes, they are heat treated. I doubt if the hardness is all that
good at the edge though. For a sword you can figure there has to be a
Try this place out I have personally handled many of their swords and
found them to be of good quality. Heat treated by hand and sharpened
per buyers request.

Seconded -- with emphasis.
I know Tinker casually, and his blades wistfully.
I have personally handled one of his Viking-style (similar to his
2002-076Xa) that he differentially tempered. The sword was light in the
hand and perfectly balanced -- for me at least. Its owner took a piece
of 1/2-inch square mild steel and shaved nice, curly chips from it with
no apparent harm to the sword's edge. (Still popped hairs)
I don't know just how Tinker did it, but that one was the only
Viking-style sword I've seen with hammons. (sp?)
It'd be worth the rental price! :)
I cringed when John touched it to that piece of steel, but the sword
didn't seem to be the worse for it.
I don't think John would do that often, but he did it once. I watched. :)
