Speaking of cryo treating razors, has anyone tried this?
It'd be pretty expensive. Henckels probably cryo treats their razors. They cryo their kitchen knives. Or was that another company....Quote:

It would be cool if someone with more experience wanted to contact them and send a sacrificial razor that they know well (how it hones up, how it shaves, how long the edge lasts, etc) in for treatment, and see what happens :shrug: If not, I'll probably try it at some point when I'm much more confident in my ability to discern potentially subtle differences in honing, shaving, edge retention, etc.
i knew this looks familiar
I knew the info was somewhere....lazy people in the chat room who can't do searches.....
You know who you are.
I believe Henckels "Friodur" is the line that refers to the cryo process, as in "freezing".Quote:

It's possible that all the dubl ducks are cryo treated, but only the wonderedge bragged about it. This would be consistent with the statements by that dd guy that claimed that all the razors were treated the same way.
Maybe it's my imagination but of two Goldedges, a Satinedge, Hand Forged, and a Lifetime I found the Wonderedge more work to get an edge on and it was in better condition then the others. :shrug: I attributed that to the cyro hardening.Quote:

It is illegal to sell cheap crap as premium, but not illegal to sell premium stuff as the cheap stuff. To save money by not having to have three seperate production lines, they just churned out the premium tape, and packaged it as three seperate price points--it was all the same stuff!
That's fantastic, I'm going to remember that story.Quote:

Regarding the cryo treatment, I have cryo tempered DE blades, thanks to my ready access to LiN in my lab. I gave 5 cryo and 5 regular blades to my wife, she numbered them and gave them back to me, and I was able to identify the cryo'd blades due to their lasting twice as long. I asked Mike Blue, at the MN get together, about cryo tempering. He did not think it would be of significant value for straight razors. There was an earlier discussion of cryo treatment here. The thread also has links within it to other cryo threads.
It is tempting to cryo a few Wapis and Double Arrows and then compare them to regular ones.
Did a search about the subject over at the sword place. The smiths are in agreement, cryo treatment does have advantages, but its almost worthless for carbon steel. The steels that will receive the most benefit are really complex steels. They gave the example of the 10xx line of steel not needing cryo at all.
Made sense to me. And they concur with Mike in his threads here.

There is a cryo treatment place here in Mass that does it for $100 a batch. Myabe worthwhile if I were doing a batch of 10 razors...Double tempered Double Arrows:hmmm:
Are DAs ans Wapis made from stainless? I think most smiths agree that the greater the complexity of the steel, the greater the benefits. Therefore, SS would benefit from cryo treatment.
I have one razor I would like to add to your batch if possible. :wQuote:

Sure....Quote:

Theres different alloys of carbon steel. I doubt its made from 10XX. The smiths agreed that they would never bother with cryo treating 10xx.Quote:

Either case, I'm pretty sure its a marketing gimmick and DD did it because it was new technology at the time and no one understood the benefits completely. Thats my conclusion and I'm sticking to it.
As for the edge retention characteristics, its probably just made better with much better QC and a much better heat treatment. Therefore, cryo is just a sales gimmick.
Thats my theory and I'm sticking to it. :fim:
Yup. Took the words out of my mouth. Basically just SS technically benefits from cryo.Quote:

I hate to point out the obvious but I don't read Cryo on the Wonderedge we are assuming that ...
The new Dovo #105 claims Frozen temper too....
I believe that maybe we are assigning today's technology to yesterday's razor???????? :shrug:
"Deep freezing at extremely low temperatures." Sounds like cryo to me.
edit: I'm open to suggestions, but I really see no other explanation. Deep freezing at extremely low temperatures is exactly what we call cryo tempering (or whatever the correct name for it is). Drop the temperature of the steel below a certain point. Thats all cryo treatment is. Until a better theory comes around, I am sticking to the freezing theory.

Just a guess you realize, not that I know anyone who actually does this....:w
