Until Nathan posted the video of him bending a K18 90-degrees, and it returning to true, I had NO idea the K18, (and in fact, D3V) could do that.

I believe I posted about medieval swords. The folks who study them, have done things like hardness test a whole lot of them, testing the edge hardness every 3cm (5cm?) down the edge, and found that
1) medieval heat treatments weren't particularly consistent (to be expected, with coal forges) and edge hardness in the same sword would vary on different sections of the edge
2) in general, hardnesses for swords varies between the mid-40s to mid-50s HRc, with hardnesses in the high-50s HRc being less common with European swords.
3) with the differential hardening in Japanese katana and tachi, the highest recorded/tested edge hardness was 61 (maybe 62?).

The softer hardness European swords could flex quite a bit and still return to true. While Japanese swords could flex a tiny bit, flexing/bending them more than a little bit would result in permanent bends (which I've also previously mentioned seeing happen with a single botched cut on rolled tatami, made with a $$$$$ authentic Japanese katana).

D3V is 61.5 HRc IIRC, which is as hard or harder than any historical swords. That it can flex 90 degrees and return to true, is mindblowing (and makes me even more excited about the K20 šŸ˜).

very interdasting
 
Sent my son home with a Keppie this weekend. Quite a jump from the Mora I gave him previously.

Heā€™s putting it to use right away. Seemed like a good pattern for the HVAC work heā€™s doing. He tends to break the tips off folders.

Starting to get tired and need to pace myself šŸ¤£
This is probably the most use any of mine will get for a while.
Had a cool piece of Trench Art years ago that had a Bowie style brass blade soldered onto a round that wouldā€™ve been great for letter opening, but gave it to a friend so figured my Kep would be good for it.
