I just started my first full project for a "fantasy" inspired Pudao polearm. Now that I'm at the last steps before I have to get it hardened, I have asked myself: Does the tang need to be hardened? After that I watched some videos and actually saw that a lot of smiths dont fully heat the tang or even heat it at all. How about modern production swords? I know that DH blades dont't have a hardened tang, but what about TH? Is there a big difference between a hardened and unhardened tang? like shock absorption? If yes I would need to inform the service where I want to get my head hardened to not fully harden the tang (I know they harden knives, but I don't know if they regulary have to harden a polearm head where half the piece is just tang ) Whats your opinion on this? If there is already a thread on this kind of theme, I was just to stupid to find it (and lazy).

I think that the hanwei tinker line have the tangs left softer so they can absorb shock better. This leads to less breakage at the hilt i think

Afaik tangs should be much softer than a TH blade, probably not quenched the same way or perhaps tempered much softer afterwards.

I recommend you either have them not harden the tang at all (except for the tang-blade junction which should be heat treated though best tempered softer than the blade) or draw the tang back softer than the blade. The first option is usually the preferred one and comes naturally as you hold the blade by the tang when quenching so the tang can easily be left out of the quenching medium.

Now that I'm at the last steps before I have to get it hardened, I have asked myself: Does the tang need to be hardened? The tang doesn't need to be hardened. The haft should fit the tang closely enough so that the tang shouldn't bend past its elastic limit even unhardened. That said, it would be good to harden the tang, and temper to an ideal spring temper (which will typically be at about HRC45-50).

Yes I agree with Lukas, I only ever quench the couple of inches nearest the shoulder, always leaving the pommel mounting annealed. Then draw the shoulder area to a lower hardness than the blade - or at the least make sure it's very thoroughly tempered.

Thanks for all these responses, they help me a lot.
Because of this I tried to get in contact with the place I want to get it hardened. Now I only have to wait for their response.
If everything works out I will try to post some pics of the polearm when it is finished. (could take some time, because I don't have a lot of time myself at the moment)

Wish you had of contacted me about heat treating it for you.

yeah would love to do it so, but I live in Germany so I guess I would need to pay around 60 dollars shipping to you, then again back and then I still don't know if I have to pay any taxes. If I were to live in the USA, you would have been my first choice

Perhaps Lukas MG?

Ok sorry didn't know, Lukas doesn't heat treat.
I live in Nukaya Oklahoma.

Yup, Driggers is right, I don't heat treat long blades yet (though I'm building an electrical oven right now). In Germany you can send the blades to Schmiedeglut.de. Or to my current heat treating guy, Daniel Rosenfeld (he lives in Luxemburg, you can contact me for his address, etc).

I don't heat treat long blades yet (though I'm building an electrical oven right now). Ok, now it becomes interesting! Let us now about this with an extensive thread about this, when finished, please. One of my dreams concerning the next years projects. And yes, Schmiedeglut does a good job, I think. I have no comparison to them at the moment, but I'm absolutely satisfied with my last two projects.

I can't promise that. I have zero knowledge about all the electrical stuff hence I'm doing the build with a good friend of mine who does. We'll essentially live in the workshop for some 5 days and hopefully it'll be done by the end of that. I'm not sure if I'll be able to take much in the way of pictures.
