I want to try some more stock removal and I'm looking to work with steel (pre hardened) that is around 1/2 inches or 1 cm thick (close enough). The thing is, I can't seem to find stuff that is more than 3 or 4 mm thick in the EU, or when I do its usually less than 0.5% carbon, so its low hardness.
If anyone can point me in the right direction I appreciate it!

Why do you want it pre-hardened? You know that it is a pain to do stock removal on already heat treated steel and that it requires particular equipment to get it done without ruining the heat treat and/or taking forever?

All of us that do it I think are in the USA. Even as cheap as my price are shipping would drive the cost to high.

There certainly are guys offering heat treating services in Germany. Not sure where the OP is from...

Lukas has a good point, trying to cut and grind pre-hardened steel is a huge pain. (I think) Even knifemakers working with prehardened steel still cut the profile out before heat treat. In my limited experience, it takes me about an hour to grind an ounce of hardened 5160(slow and methodical, making sure not to ruin the temper).

Portugal.
I know its going to be hard. I work with files (make knives out of files) and its tedious, painful labor. I want to retain artistic licence though. I have looked into getting a blank heat treated but what gets me are the shipping costs for that heavy, oversized blank. Even just in my country they are high. These are the main problem. I was wondering if I could scale up the work and what kind of cheats I could use on it (waterjet to blank and mill faces mostly). So, if anyone has any ideas for pre-hardened steel I'd be very thankful.

Google hardox steel. It's available in various thicknesses and hardnesses. My friend and I made a few blades out of it, but the retailer cut the basic shape with a plasma cutter.

Like what Michael Chtulhu uses on his giant swords...? Never thought of that. I get the feeling that it would somehow be more difficult to finish by hand than hardened 1050 steel...

It seems all the workarounds lead back to the same place: figure out how to do quality HT at a low cost... Anyone got any plans for an induction heater suitable for sword ht?

An induction heater in sword length is gonna be many things but not cheap. If you want to/must do it yourseld, the cheapest thing that could work would be either a long trench style forge or a drum gas forge like this: www.bladesmithsforum.com/index.php?/topic/32608-in-search-of-an-improved-ht-apparatus/You'll still have to figure out tempering. Doubt your kitchen oven is long enough for sword blades. A hot oil bath is a cheap possibility. Or a long pizza oven? I even know of one sword maker who takes his quenched blades to a bakery for tempering... In the end, nothing beats an electrical kiln (well, maybe salts, but those are scary) but that is hugely expensive in Europe or impossible to get (I've tried) so building yourself is the only option. I'm doing that at the moment. The materials alone are well over 1000 Euros.

I was quoted at 4500€ here in Portugal. I've bought several books on how these kilns work and how they are built but I cant even get the correct firebrics! The elements arent actually that expensive and neither is the PID.
If you succeed in building it please post the basic steps you took and the problems you had.
