Saw chain staying sharp twice as long?

[ShoerFast]

This could be something that would benefit saw-chain?,,,,,, my gears are turning on how to freeze some honed saw chain just to see if there is an advantage,,,,,,,,,

It could be offered as "Extended-life" or EL saw chain.

Good thread, but no one has tried it on chain that I had seen.

It just has to work,,,,,, if it improve wear life 200% , without doupling the cost, it may take out hand filing as an option, but with all portable chain grinders out there, this might work?

Cryogenic Process

I for one am well familiar with this process. I did a collage paper on it. By the way, I received a (B+). I also did a post on this process in this forum about 2 years ago. Many negative replies. Are you aware that many Knife makers send their products to have this treatment? gerber, Ole Henery and certain Buck knives have had this. Personally I had my whole kitchen cutlery treated. I have not had to sharpen at all.
As to having chains treated, I am all for this. But being only a small time saw addict I could not justify the experience.
Golf clubs respond well as well as metallic musical instruments. Hospital surgical instruments are treated as well. The cost savings are well justified.
I hope that you have many positive responses as most of mine were negative.

I'm thinking a timmed test with honed chain would prove it's effect as fast as anything. By the clams, all well proven, it would have to work.

My other main hobby is being an amatuer musician. Did a lot of reading on cryogenics and brass instruments, never saw a good double blind test that proved it worked. That said, some people swear by it.......

Always figured leaving a horn out in the car here (with some minus 40 wind chills) did the same thing, just took a little longer!!

This is proven technology. My mother in law runs Cryo Plus in Wooster Ohio. It is a very good process especially on rifle barrels. normally we get 1500 ti 2000 shots before accuracy dropoff, now we get upwards around 4000 to 4500 before dropoff. The barrel also cleans much easier.

My concerns would be cutting dirty wood even lightly dirty wood.
Would the edge dull or would it chip or even break?

Send me 60 drivers of Stihl RS .375 50 gauge.

I smell a test.

We used Liquid Nitrogen on h.s.s. drills & milling cutters in the 70's, with a slight gain in cutter life. It wasn't worth the bother in the end.
From reading the info in RB's link, it appears that that the most gain is achieved by a slow cooling cycle.
My question is............. how to attain the slow cool with liquid nitrogen, other than a full quench, without wasting volumes of the liquid while exposing it to room temp.?
