I can give you some tips. Thanks very much, but my previous posts were made in jest, I wasn’t trying to steal your secrets. Where you start at 10° thickness permitting I do so at 15°, the limit of my sander. You had told me earlier about your final 30-35° polish. Again my sander limits me to 30°, but over time I’ve chosen 25° as a general setting. I’ve found there is a difference in performance with a higher polished blade so the final polish is with metal polish with a leather strop. Unfortunately my swords for the most part lack a good HRC number with 50 being a good representation. So I try to hit a happy median of performance and survivability. My weapon/tools such as the puniti and machetes will go 60 and above. Again I wasn’t really trying to steal your trade secrets but the info is appreciated. That's a problem with the Internet, it's hard to know when someone is serious or not. I had attached smiley faces in hopes that you knew I was joking. Have a good day. No problem. I consider you friendly enough to share with, all along the years of appreciation for my posts. :D

Hi Lancelot Chan I think a core concept of yours, from this and your other posts I have read, is you go for an acute angle as far out as the edge supports it, but from there, which could possibly be the very apex, switch to a more obtuse angle. This would be to try to get the best of both worlds, slicing vs hardiness. Not to oversimplify of course, as you optimize further (ex, micro-serrations). You are the man when it comes to cutting! Thanks a lot. Yes, that's the concept. I did a lot of experiments and had sacrificed some of my swords' edges along with those trial-and-errors. I figured out that even 3V or high hardness 1095 at over 60 HRC, couldn't withstand cutting living bone hardness without that invisible micro bevel, lol. I wish I knew earlier, man... the result was ugly without it. Gosh... My latest swords were more fortunate for not having to conduct with "academic experiments" like their predecessors.

LK Chen's white arc, sharpened to my standard, but not to the degree of "geometry modifying" like the cold steel grosse messer.
I performed this on the sword owner's request. I told him "You really think it would work?" beforehand. He may have thought that just every sword could do this. So yeah, let's see.....
Failed.

In the name of good will and international relations how about an free online tutorial? 😉 If you manage to convince my landlord not to charge me rent for 1 month, I can do it. Give me your landlord's name and I'll send around a few of the boys to "discuss" with him a month of rent forgiveness. I'm sure we can make him an offer he can't refuse....

That's a problem with the Internet, it's hard to know when someone is serious or not. I had attached smiley faces in hopes that you knew I was joking. Have a good day. For your interest, I actually compared using just 20 degree per side with no micro bevel to my finalized method. The 20 degree per side with no micro bevel performed worse. It has larger cutting drag due to the angle, and then it doesn't hold against the hard target due to 20 degree not being strong enough. So while it is more common out there on swords, it does not perform as well as my "less popular" method. My method (the acute angle + micro bevel) somehow combined the smoothness of cut and edge holding ability.

Thanks for the info, it’ll save me from experimenting at some point in time. I’ve been satisfied with the final 25° not to go more acute. I got the idea from a soft metal machete, the one I use for the crappy jobs. It never has held a edge well but I found this an advantage as it sharpens easily and has never chipped where rocks, cement and such are concerned. It’s also my loaner. I tried 25°, something I estimated greater than I had been putting on by hand. I may have gone more acute when first checking out my sander. With that working I advanced to 30° and that held an edge better but in the long run I found the 25° more satisfactory. Most of what I’ve read suggested something more acute on kitchen knives but with the way Hazel abuses an edge I give her 25° also. That woman has no feelings or respect for a knife. So the final edge I generally put on now is 25° as I’ve had good luck with it on swords also. I admit in some cases I’ll make the final pass or two at 27½°. Come to think of it Hazel asked for resharpening yesterday and I obliged. After which I made a few passes with my bowie work horse, not that it needed it but was a good time to freshen the edge. It could not been more than a half dozen passes. After which she saw me checking my work by shaving my arm and she had to make some commit. I had done the real check previously with copy paper and all saliently and effortlessly passed through. But somewhere along the line I learned to shave as a test before the paper came along and from time to time still use it. Besides shaving sharp sounds more impressive to, me at least, than paper cutting sharp. This has gotten much longer than intended, so have a good day.
