Not true at all. We've been over this misconception many times. I guess I should have said "in my limited experience" If this is been discussed before, could you point me in the direction of those discussions. Jon Here's where it starts. Look at the date. Work forward from there. None of the basics have ever changed. sbg-sword-forum.forums.net/thread/2746/differentially-hardened?page=1

Putting aside whether or not a hamon is necessary for it to be called a Japanese style sword, there's no free lunch. Edge holding versus toughness. I know that's an oversimplification, but in my zombie apocalypse I would bring a through-hardened blade and a whetstone. 😲

Hey treeslicer is there any particular longquan place you would recommend to buy from like a link to your preferred DH water quenched folded steel katana?

I usually look for folded blades with lots of "activities", including ara-nie, ji-nie, sunagashi, kinsuji, inazuma, etc., in the ad photos. There's only one way to get that sort of thing, and it's water quench. Gunome hamon seems to be the best done in Longquan. See a couple of my eBay Chinese blades below (the bottom one's a nihonto).

I think that's a good idea! However the most durable blades are going to be through hardened TH literally means cracks propagate throughout the entire interface bc there is no change vs hardened with yo where the quick change in structure means a crack remains limited It also introduces a problem where either your sword is too hard and explodes or is moderately soft and has accelerated edge wear.

I know that's an oversimplification, but in my zombie apocalypse I would bring a through-hardened blade and a whetstone. 😲 Narrow suguha with soft protrusions like yo pretty much is the canonical solution. This is why traditions known for making hard to break zombie swords like Hizen used it. So did the IJA during its war as it mandated RJT gendai and mantetsu use suguha that isn’t overly wide. The wide soft part of the sword provides good support while allowing good retention. It gets even better if Utsuri is around to give the steel springiness. Realistically it wouldn’t matter much since there shouldn’t be an apocalypse and if there were my collection of guns would be the first resort. I guess if there were a Wendigo apocalypse the swords would also be main weapons?

I think this was gone through in the previous posts. Through hardened can make a very durable blade, the same as differentially hardened. I don't think a through hardened blade would have any different crack propagation than a differentially hardened one. If done properly, the DH blade is basically like a cross section piece of the TH blade. Soft steel inside, hard steel outside. Either way, if done right, it's going to be pretty tough. Either way, it can break with the right forces/pressures. My choice, however, is for a DH blade, because I'm into Japanese blades and I know them well, can do everything I want with them. That being said, I have a through hardened Dojo pro. If I was to harden a blade, I'd do it DH, because that's what I know (going to do a bunch of Yaki-Naoshi next spring!). So, if given the choice, I'd go with familiarity like I do for myself, and not worry about which one's "tougher."

As always perfectly heat treated examples of the favorite method are compared with the semprini examples of the other method.

If Japan had some decent ore to start with we might never have been blessed with the tradition of water quenching and differential hardening.
