Hi Scott,
Thanks for the invite! I'd like to meet sometime and get to know a fellow member and talk razors and hones. Right now I'm getting over a cold and my wife is just starting it. It'll be awhile until the bug fades from the scene. I wouldn't want to pass it on. Caught it at my daughters retirement ceremony at McConnell AFB, Wichita, KS. She retired as a MSgt with 24 years service. I will PM you when things normalize a little and give plenty of time to make it convenient. Thanks again!

Best Regards,

Howard

I thought about trying to do a dual bevel before ever reading about the unicot method because I remembered seeing a special on the show "how it's made" about how they make a few bevels on disposable razor blades as they progress getting smaller each time. I have been getting my best shaves lately off of using a double bevel, I finish through the progression as normal then when I would be normally done tape the spine and finish. I'm a believer, would love to try it with a 30k.

On another note since seeing that with disposables they actually make 3-4 bevels I tried doing the same adding an extra piece of tape after the second. I had a decent edge but nothing noticable, but I only tried it once. Maybe that's something I should try a few times, maybe see if I can get some others to do an experiment with me? :P

I have done a bit of thinking on Double/Micro bevels and have come up with exactly One (1) use that they could be used for in my mind...

Re-freshing the razor, this is the only time I can think of that a micro-bevel would be advantageous, it would create a slightly steeper/stronger angle and require much less work/laps to achieve, it would also create a bevel that was entirely done on the finisher.. It would also assure that the person doing the refreshing was getting to the very edge of the razor..
When the Micro-bevel is no loner achievable it would be time to rehone the razor again, this would possibly extend the time between full honing and give the best shaves for the longest time...

Personally I don't think the fact that DE and Disposable blades are created this way is a good reason to follow them
They start with much thinner and harder steel then we use *in general*

I was by no means compareing DE's to straights. I just thought it was interesting as an experiment and the unicot is based by similar means. What you said about setting the second micro bevel as the last step on a finisher, I agree totally. I would be interested in seeing different methods of multi-bevel edges with a microscope.

I use Zowadas methods and love it,My question is: Scalpel blades have multi bevels,DE blades use them,The blades we use in the pathology lab for sliceing tissue in preparation for frozen sections use them,Diamond blades used in eye surg. are lapped with multi bevels,,,WHY would really like to know.

My guess would be to shorten the bevel which in turn would strengthen it and cut down on chipiness, which you would not want in a scalpel (contamination), or even a disposable blade (longevity). Just my guess though!

You may be right,disposible scalpel blades are only good for cutting tissue,one time,make a skin incision,they are dull,very sharp for sure but very fragile.

Cost! Only the very edge of the tool gets polished to the final grit, and the primary bevel stays rough ground. Faster, and cost efficient. Set a bevel on a 1k stone, put 2-3 layers of tape on it, do 20 passes on a finisher. Now, do the progression from 1k up to 12k with only small jumps. You need more stones, more laps, and in a factory this equals to more tool wear, and slower production. A tool will cut almost the same if it has the whole bevel polished, or only 1/50 of it. Thats why they use more bevels.

Agreed,Thank you.

Interesting, you got me to thinking about a two stone method that I have never tried with my GS stones: Set the bevel without tape one the spine @ 1K, go straight to 30K with tape on the spine. ANyone done this yet?
