On a lark, I purchased a 10 pack of wilkinson sword DE blades that had been cryogenically frozen from greatrazors.com. Their claim was that the super cold treatment would increase blade life. I didn't really believe it. I still don't. However, I am now on week 3 on a blade that normally gets tossed after 3 shaves.

Anybody else give these things a try?

Justin, they sound too good to be true. Are you shaving every day? Wow, this should be an interesting post if more gents start trying out the blades.
Thanks for the information.

I ordered some of the Wilkinsons to try also (and I ordered enough that I can probably send some to other interested guys at less cost than buying ten of them from the site). I'm going to compare their qualities to those of my vintage Wilkinsons. It should be interesting. I've never seen any objective proof that the cryotreatment increases blade longevity, just their website testimonials and your very brief experience. Some years ago I had some Weatherby rifle barrels cryotreated, and it improved their accuracy significantly. However, until I actually try these blades, in my mind it still will be in the same category as magic pyramids.

Justin, i just ordered a pack from them. i know i should have waited, but it was only $7 shipped to Vancouver, so what the heck.
If i get the same results as you, then i will post a thread and order more. You know, if this turns out to be true, then you can expect their prices to increase significantly once the word gets out.
Let me know what you think of them, John.

The only reason I can see them having any benefit is if the heat treatment isn't as good as it could be from the manufacturing.

It really shouldn't have any effect at all on longevity. I think you gents should do a blind test.

Sounds like a great idea, Lee. i wonder if i can get my partner to help me out here, but i doubt it as i get up to early for her. Maybe i can convince the cat to help me out.

I'm not sure I would trust a cat with razor blades, Celestino.

Just have her give you the blade. I'm sure they look the same right?

I don't have a handy phase change diagram for stainless steal nearby, but I can't think of any changes to the internal structure of the metal that wont be undone when it turns warm again - even less so when it's a thin sheet like a razor blade.

I'm genuinely curious as to the metallurgic reasoning behind chilling the blades down to - according to their website - minus 185C (88K / -300F)... seems to me, based on the temperature, they are dipping / soaking them in liquid oxygen. If it's just a gimmick it is an expensive one, that is for sure.

I have a friend who is a Distance shooting competitor,he feels cryo-treatment has some benefits.I think the theory is it causes a closer alignment on a molecular level.If so I could see the benefit to a cryo-treated sharp edge.

I'll have to keep an eye on this thread.

Interesting.

In other disciplines, cryogenic treatment, while maybe not scientifically proven, has quite a bit of anecdotal evidence to support the restructuring of the crystaline structure of the metal, yielding increased life. I'm thinking gun barrel life, but can't discuss it in detail (rules of the forum). To condense it down, I've heard good things about it over the years.

If I can get interested in saving a few pennies (doubtful) I can replicate this and treat a few barrels at the same time. It only takes liquid N2, which any welding supplier has available. It's no big deal, it just takes special handling.

What was the price of the treated blades? Cost effective or not? That is, if it cost 5x more to get 3x the life, it's not worth the expense IMO.

The math on their website claims it's significantly cheaper - provided you accept their claim of increased longevity.

For a long, hollow cylinder the benefit I know of when it comes to cold treatment is the removing of stress, thus reducing warping - several parts of the jet engine in the F-16 is cryo treated to remove stresses before installation.

So, it clearly has benefits for cylindrical objects such as aero parts & gun barrels.

But it has dubious benefits regarding edge longevity.

I should like to point out to the forum that the Dubl Duck Wonderedge was cryo treated and it doesn't last any longer than the Goldedge.

Without a double blind test, the results are always going to be tainted by perception.

It cost me $15 for 50 blades, including shipping.

Try storing your blades in the freezer for a month and then use them. They will last longer I thinkBiggrin

Kidding aside I did buy blades once from this company and I not sure if the blades were any better.

Like I said, I don't really know that I believe their claims. They definitely ring in the too good to be true column. However, I will see how things go. I have been using the same blade in the same razor since the Monday before the first day of school. So, August 20th. Monday this week actually started my 4th week on this blade?
3 weeks down... odd...

So, 3-4 passes each day, so the blade is looking at at least 63 passes on it.

I was sloppy (falling asleep) while shaving and nicked myself a little last time. Looking at the cut, it wasn't a nice thin nick but more of a cartridge style cut. So maybe at some point I started applying pressure to compensate for a dulling blade. Maybe... maybe not.

I don't know.. it could just be a freak blade. Dunno, but like when Joey and Chandler were afraid to change the channel or they would lose the free porn, I wonder if I change the blade if I will end up with nothing but crud blades.

I can't believe that I just made a Friends reference.... Now I go sulk in shame

You could give a friend a pack of regular blades and a pack of the cryo blades. The friend (or SO) would then sharpie the blades with a number or letter corresponding to which type they are. Treated or not. Then, only they would know which was which.

You do your experiment and report your findings, then the friend reveals which one is which. You can even have them put it in a sealed envelope to be opened when the experiment is done in case they forget.

You just can't watch them mark the blades.

Sounds like a good enough way to do the double blind test. Well... close enough to double blind at least.

i am really enjoying this. i am looking forward to the blades so that i can experiment. i will try my best to do a blind test, but i have my doubts about the cat's ability as she has better things to do such as sleeping and eating. i will report back after conducting the tests. Regardless, can't i just use the blades until i feel tugging or not getting the smoothest of shaves?

Justin, i would never have thought i would have heard a Friend's reference on a shaving forum. Wink
