Great points.I only reloaded once and I was still on page 2 (even if just barely). This was pure adrenaline, which honestly is a lot of the fun. I bet Nathan didn't think he'd have a preorder thread fill that fast! That was almost certainly going to have been a sellout in less than 60 seconds once we account for the two-sword orders.
I think you had two things working there, one, after you delivered the K18s a lot of people got to kicking themselves for missing out, and two, a modern wakizashi would probably always have been a popular design. I sure am glad you had the stones to do this though, I'm sure it'll be a tough project, but a wood K20 will absolutely 100% be the centerpiece of my knife collection forever (I guess unless we get an integral dagger preorder, in which case nothing lasts forever, you know), and unlike the K18 preorder this time I was sure to get two so I can have one to actually cut things with as well.
I was in, and already hyped for the K18 when the concept was still being bounced around. I knew it would be great once Nate announced that he was collaborating with Dan Keffeler, but even I was amazed at the flex test video that Nathan posted (not to mention Dan 1-hitting a 2x4, and Benny demolishing a cinder block).
D3V is generally ~61.5 Hrc? Medieval/historic European swords have been tested to vary between low-40 to high-50s Hrc, often, with varying hardnesses on different edge sections of the same blade, tested at 5cm intervals (heat treatment not being as refined/consistent as modern equipment is capable of).
Differentially hardened historic katana have been tested to show an edge hardness as high as 62Hrc (there aren't any documented/confirmed tests of any katana with hardnesses higher than 62Hrc that I'm aware of), and traditionally, with the clay differential hardening, a softer spine around 40Hrc (for impact absorption and a little give/flex).
That said, NO traditional/historic katana would survive a 90 degree bend intact, like Nathan showed in the K18 test.
I posted before about a classmate in Kenjutsu, with more money than skill/brains, who ignored the instructor's recommendation to NOT use his $10+k genuine Japanese Shinken for tameshigiri (cutting practice), and to buy a cheaper practice sword specifically for cutting practice.
He botched a cut on a 3 (IIRC) tatami roll, and permanently bent that gorgeous sword (and I don't think there was more than maybe 20 degrees of blade deflection, that resulted in the permanent bend. Definitely not even in the same continent as 90 degrees of deflection).
When Nathan says that the K20 will do things a traditional sword can't, he's not kidding.
*** OK, OK, so I didn't post all this until after the preorder was over
