Very impressive, how did you achieve it? What angle are you using, describe your process.

I first use a 70grit Lansky stone (discontinued, no longer manufactured) to establish the edge bevel, basing on the original primary bevel and add 10 degrees to it. I used to use DMT XXC to do it but the XXC is so heavy so it's taxing my arms very much, since I do all these with the stone hand held, sword vertical style. I have since then switched to the lighter, faster lansky extra coarse. But the lansky got used up much quicker than the DMT was. So I will switch to something else once I depleted all my lansky stones (I got 5, used up 3 already). Usually my bevel would end up from a very acute cutting sword at 30 degree total, to stiff thrusting sword at 60 degree. The edge will be very slightly convex, due to free hand nature. I would keep it as flat V as possible, though, since the later grind will make it more convex. I'll also correct the mistakes from the original grind on this stage, like asymmetrical bevel. Took a lot of effort there.
For example, the tinker sword was 60 degree edge, while my DS are mostly 30 to 40 degrees. The angus trim bastard sword is maybe 40 degree total.
I'll work with the first stone until the edge line got touched. This takes the most time and stamina. Then I will move to DMT XC 50 strokes with double directions, then C, then F, then XF, then XXF. On each of these steps, I would ensure I touched the edge line as well as polished the bevel surface with the stones. Usually it means I would have to divide up the 50 double action strokes to a few different angles to make sure I got the spots all covered. I'll check every time if the burr was flipped to the other side. If so, it means I've covered the edge line with the stone.
Finally, I use a corrugated cardboard piece to strop the burr off and made the edge "glassy" reflective. Usually it takes around 5 alternative strokes or more, depending on the steel hardness. That's how I did it.

Hiu Tung Chan used darksword danish 2 hander and Edwin Chan used Longship Armoury LLC John Lundemo made Zhanmadao that I designed, to practice cutting from the sparring stance.
As a result, we figured out that the darksword danish 2 hander needed to be streamlined in the edge profile to facilitate such cuts.

My DMT coarse six inch has gone to an x fine over the years. It was used too much for stock removal to reprofile blades. I have a Lansky diamond as well that has become a super x fine. As a result lately I have gone back to files, regular carborundum and a large aluminum oxide bench stone I have ground a lot with. One of these days I will get a belt grinder. Not surprisingly, my natural Arkansas and other natural stones have lasted much unchanged since the 1970s for doing fine edges. I am liking the two sided Lansky Puck for blending swords.
The DMT stuff is great but I won't buy another for basic stock removal.
Cheers

Nice videos Lancelot, those 2-handed Dane cuts are really great. Looks like you took the sword to the next level.

Hhahahah you're the guy who knows how I feel now! My stones go through the same and eventually even revealed totally flat surface at heavily used spots, since the diamonds were ALL GONE!
I can't use a belt grinder since my wife is allergic to noise and dust, though. With hand grinding, at least it's only dust. 
But thanks for sharing. Good to see ppl who have the same feeling.

Thanks for watching. Yes, with this edge reprofiling, I get the most out of the swords by turning them into their best state. ;D Still battle edge profile, just the sharpest battle edge. A flat and thin appleseed.
