just got a Millie CF/S90V!!

I thought phil wilson ran S90V around 65.

He might, but I don't think so. Even 59-61 is considered hard for S90V. From his "seamount knifeworks" website he says:

The CPM steels, (Crucible Particle Metallurgy) makeup the largest percentage of my production. Both CPM S90V and CPM S30V have a high percentage of very hard; very fine Vanadium carbide particles in the steel matrix. This combined with enough Chrome to make them stain resistant make them ideal blade steels. CPM S90V was introduced in 1997 as an upgrade for CPM S60V. It has a higher attainable hardness for improved wear resistance. I worked in conjunction with Crucible Materials to pioneer the use of CPM S90V for knife blades. I remain one of the few makers currently offering it because very few are set up to heat treat this grade. I built a high temperature, precisely controlled furnace and developed the techniques required for consistent results. I heat treat CPM S90V to a finish hardness of (59-61). CPM S90V is the choice for the ultimate hunting blade.


Crucible about S125V
CPM S125V is a high performance upgrade to CPM S90V.
With 12% vanadium, it has superior wear resistance while
maintaining similar corrosion resistance. S125V has the
highest attainable hardness of any CPM stainless steel. It
is available only as CRU-CLAD.
CPM S125V is supplied in the annealed condition at BHN
280. Its typical application hardness is HRC 62-64.

BTW, I'm willing to rule out the Byrd wrench at an un Byrd like $83.95 if you are. It goes against the whole idea of this being cheap & fun. :) Joe
 
The duckfoot sharpener, unless you want it to be a knife? I can pick a Byrd knife if you prefer. Joe
 
I recently had the chance to play with my father's CF S90V Millie. I was doing some comparison testing in cardboard and sisal rope, along with S30V Para, mini-Ritter, Buck AG Crosslock, D2 Dozier, D2 Queen, and Fallkniven U2. From the way that it felt on the diamond stones when I resharpened it, the S90V Millie isn't any harder than the Dozier D2. I saw the RC 65 quote before I did that, and was expecting a harder blade, but in my experience it was not that hard.
 
Hello, just ran across this post. If Sal can get S90V to 65 I would sure like to know how he does it. My experience is that even at very high temps the max as quenched hardness is about 62. Any tempering at all and you are down to around 60 at the best. The only cpm steels that can get up into that range are CPM 10V (64) and 125V (64/65) or maybe CPM M4. If you really want to know the actual hardness send me the blade and I will Rockwell test it for you.. Phil
 
I got one of these on the way. I bought it because, it's a sprint run and I like collecting those and the blade looks to be highly polished, much like my CF Caly. Now with that purchase I'm gonna stop for the long winter. (I think, well maybe. I'm at 34 Spydercos and it wasn't a year ago I had just 14!)
 
Just got the Byrd Knifenut 1013. You're a gentleman, and a man of your word. I'm thinking I messed up and should asked for one of your incredible sharpening jobs like you did on your mule.

Live and learn.:)

Thanks!

Stay warm up there Brother, Joe
 
I sent you a PM, you got it right?

Send away, I get board sharpening my sharp knives.

Its colder sooner this year and I think were in for lots of snow.:(
 
I got your PM. It'll be a while probably, but thanks!

It's been pretty cold here too. We had snow the other AM, but it melted.
It was 14 degrees F down in my little valley here the other night. 29F the night before, and the one after. Cold pools down here where I live in this little hidden valley in Raleigh.

I knew it was going to be a strange year. We could have anything from below freezing, to 70 plus degrees F this time of year around here. We're in a cold snap now.

One year we had 23 inches here, plus drifts in about 8 hours. It was like being back up north, without the snowmobiles and open stores. I recall one february where we had thunderstorms with pink lightning, and 13 inches of sleet.

Then there are the tropical storms with aqua colored lightning. Joe
