The 110 S90 v

it is a great knife. i wanted a different version when the poll was happening, but this version is a winner. enjoy yours.

I think we were close to wanting the same different version that didn't happen :( What made me cave was the blade steel. I want to see is S90V better than S30V. I do like S30V better than 420 hc . But maybe someday a better version wil show :D
 
Looking up this steel, it seems like it requires a very specific type of heat treating process.
Are there other steps involved beside the Bos part?
 
I don't get what your meaning. The 'Bos part'. Heat treating is the entire treatment of the blade. DM
 
That steel is made by Crucible in their manner, manufactured by their method, using powdered metallurgy technology.
Then that name/ coded steel is sent in bulk (bars or sheets) to the buyer. What ever he ask for. The purchaser then works
it. Cuts it into a blade, jet fan, what ever he needs it for. The purchaser is then responsible to have it heat treated as he desires
for that application. Mr. Bos could have worked out the formulas for this treatment/ steel and Paul Farner who heads up the
heat treating dept. did the work on these blades. This is the common manner the way blades are done. DM
 
It is common for the manufacturer to send heat treatment recommendations along with their product to the purchaser.
He can follow these or adjust them. DM

This was my understanding for the most part. The manufacturer will recommend a hardness range for a particular application. For example; a particular steel that is used for both bearings and blades will have a different recommended hardness. Ultimately though, it is up to the user to determine the required hardness for a particular application.

The other variable is how exactly the hardness is achieved. There are countless heat treating processes. I venture that in most commercial applications, they are all "right" for their intended purposes. The difference in Buck's case is the process in which they heat treat to achieve a particular (or recommended) hardness.

In the end, you have to put your faith somewhere... If the steel manufacturer says it works best in knives at this hardness, I tend to yield to their recommendations. How Buck meets those recommendations is where Paul Bos and his system comes in.

I've either not had, or exceeded the proper dose of caffeine this morning and I'm making this all up...

Ummm ... is that even possible?!?
I need a minimum of 2,000mg caffeine a day just to keep the head hurt and shakes away. :)
 
In those manufacture recommendations a cryogenic treatment may be stated, at this juncture the treatment can be done.
NOT with specific temperatures or holding. Buck has spent the time to develop this procedure & money to procure this equipment and keep it in specific tolerances (good working order). Which I think this treatment really helps the steel to perform. DM
 
I do not have any direct experience with S90V. I do have experience with S30V, S35VN, and S110V. I would assume S90V would perform similarly to S110V, but not be as corrosion resistant (though still great in that regard). The edge holding should be phenomenal.

edge rentention and toughness is very similiar to s110v from my experices in cutting. thats comparing spyderco s90v to spyderco s110v. i do have some bucks in s90v but none in s110v. i prefer s60v but s90v is quite a good steel for my use with cutlery tasks in folders.
 
From what I recall bos and farner didn't have an oven to reach the highest temperatures s90v needs to reach an optimal hrc value. Iirc an older thread said this as well. A recent thread said that farners oven could only reach 59-60 for s35vn or something along those lines. You'll obviously get great edge retention but will it be as good as someone elses who has an oven that reaches higher Temps? Or is this information out of date?

One could send Peter at Cedric Ada youtube channel to cut test it and compare. He just tested Spyderco's s90v recently on a manix2 lw. Which iirc from Ankersons test is around 59-60hrc and benchmades is about 59-61hrc (benchmade cuts longer in Ankersons tests BTW).

Bos do a good job regardless and 1 point won't be a drastic difference I don't think. But would be good to have a better understanding of the facts rather than wonder.

That would be kinda cool if Buck would step in and tell us the hrc they achieved with the process they used on the S90V they are treating. Maybe they send it out ?
