Will pyramid honing work with a pair of stones that are not steps up in the same maufacturers line. I would like to try using the pyramid for honing because I think I am overhoning and getting a wire edge. Will the sequence Norton 8000/Chinese 12K then Chinese 12K/Shapton 16K work? Any recommendations for the number of strokes on each?

Is the creator of those videos a member? I saw those a couple years ago and was very impressed with them.

Great vid, who s it!? The stone shouldn't matter a whole lot as long as its similar grits, as high up as you are on the grit chart, I dont think its necessary to pyramid.

Yes, he's SRP member "ToxIk". http://straightrazorpalace.com/video...s-youtube.html
Edit: I know how controversial the dreaded HHT is, but you gotta admit, his razors must be *darn* sharp to pass the HHT he does in the above video. Having a very fine hair like that snap into two pieces as shown in the video is a level of sharpness I have yet to achieve.
Getting back to semi-on topic..
When I first started honing, I was worried about over honing and the dreaded wire edge, too. So I purposely put a wire edge (as detected using the method from the above video) on a couple razors. One that was soft steel, one fairly hard. I was *amazed* at how much work it took to put a wire edge on a blade. It took a long time.. many, many laps. Far more than I ever thought it would.
The chances are, on a soft blade, that if you ever did get one, it would break off and you'd never even know it. You'd just go, "huh, i wonder how come the blade isn't as sharp now as it was the last time I checked?" and continue honing, as the wire edge broke off during your strokes.

Gentlemen,
Thank you for the feedback. I had not realized that the pyramid may not be as effective at the higher grits. I guess I will try honing my previous way (8K-12K-16K-CrOx paddle-strop) then compare it to the method Lynn suggested (8K/12K pyramid-16K-CrOx, etc. I don't have any pastes) and see what works best. As Lynn noted, I may be able to skip one of the stones (probably the 12K?). Excellent post. Thanks again.

The biggest problem in doing a pyramid on the stones you mention is the Chinese 12K. Only because it is not the most consistent of stones. You will have to experiment with let's say like 5 strokes on the 8K and then 30 on the Chinese ( Could be 40, could be 50, could be 60). Same for the drop down to 3 strokes on the 8K and then 1 on the 8K. You still need to experiment with how many on the 12K. From there if you even want to go to the 16K will be a personal decision as you should be able to go from the Chinese to a paste and then to the strop. Another alternative here is to go from the 8K to the 16K. Normally I find my most effective pyramids are between the 4K and 8K and then I will go to whatever polishing stone I am using, ie 12K, Nakayama, Escher, Asagi, Coticule..........
