Another thing to is regarding the lamination method. Either A. It's a flat out lie, because you'd be having the folded 1095 on the outside and cutting edge. Which kind of defeats the purpose of 1095 since it should be the cutting edge only I'm doing this from my phone so I hope I got the quoted part right. Hard outer jacket and edge makes sense to protect the blade edge and flats when fighting. Soft core just on the inside and spine to give flexibility.

Well, yes, but there's no point in doing the lamination like that if the 1095 is folded with some other lower carbon steel. 1095 folded on it's self wouldn't produce a very good pattern. If any at all. Not to mention, it's probably not 1095 to begin with. I've worked with 1095 and it is BRITTLE. eBay swords are rarely on the brittle side and almost always softer. Which doesn't suggest they are made out of 1095, but some other lower carbon steel such as 1045 or some such.

Don't forget there's kobuse and gyaku kobuse. Gyaku will show the lamination lines above the ha, regular kobuse will show it on the mune. www.ksky.ne.jp/~sumie99/construction.htmlI have a kobuse blade that clearly shows the lamination- I'll post pics tonight after work. Kobuse for around $3-400 should be possible as it's the most basic lamination method. Yes, there is a difference between those two types of lamination. But the ebay post was very clear with the cross-sectional picture showing regular kobuse.

Could be. Ronin has mentioned that a lot of the rejected retail blades are sold on ebay and custom blades will often use a water only process to make a hamon instead of the proper clay and water method. How this process works is beyond me but I assume the shortcut would produce a softer blade.

But I think Mike was talking about lamination lines as per gyaku at the start of this thread, and was saying a hard steel jacket was a no go when it's actually correct given the lam type

Wow, that solves that. Would you happen to have a link I can watch when I get home?

I think that was from a custom maker in... Vietnam? Somewhere like that. Anyway, it wasn't from a Chinese factory, I don't think.

I might have to ask ronin if that is the method he was referring to.

Yes and no. It's certainly possible, but to get a good hamon, you need a successful quench. And that should make it pretty hard. The only way to get it less brittle after that is to temper it. A hotter temper will certainly make it softer, but at some point you're going to start annealing and not tempering. So that would get rid of the hamon. The specifics would probably be a better question for Tom. I think the more likely answer is that they are made of a lower carbon steel than advertised. Am I wrong? Am I right? Hell, I don't know. That's just the best answer I can come up with for what I've been seeing from eBay the last 5 years or so.

I'll look for it. Don't remember where it was done but I'd bet it's done that way lots of places

Thats what I thought. A Wariha Tetsu would have a visible line. I will post pic of the Yakote later. Fell asleep after my post last night. At work now. Hey Deadly weapon. Can you post pics of the mune or just look at it and tell us that if all you see are laminated lines and no unfolded steel. Here is mune of a 100% folded steel blade. There is no unfolded steel in the middle of the mune. You guys are the expert ! Im posting 5 more pics now. Mine looks sort of like the one above. But with a thicker cleaner line right on the middle of the Mune. Mine is is polished proper and so shiny. Took me forever to take the Mune picture. More than all the pics on this post I posted.

I've seen the picture of the mune you took. Very hard to tell but seems to be fully folded. Can you take a picture closer to it like the one shown by DigsFossils? Or just tell us what you see.

I will when I have time. That 1 took me forever to take and looks better than what my eye can see. Gives my camera a hard time to focus. Blade it 11 mm wide right. I see fine lines that run along the blade. But about 3 to 4 mm from dead center of Mune is Mirror Finish. No lines.

Glad to hear that!

Glad to hear that! I sure hope so since I really love the Hamon of this blade and planing to get same one with different accessories. Its just awesome how the Hamon has a Blue hue to it compare to the rest of the blade. Blue steel
