What happened to CTS-BD30P and CTS-B75?

I would love to try out a new spyderco in b75! Almost any of the folders for me would be a go:thumbup:
 
I missed this thread the first time around.

I would love to see a Military in CTS-B75P.
My three most carried folders have BG-42, and I would love to see the powdered version on more knives.

A Carbon Fiber Military or Para 2 with B75P would be a must have for me.
 
Im a big fan of carpenter steels, xhp is currently my top 3 favorite steel, takes a nice keen edge and does it faster than other super steels, I like its cutting performance and it holds an edge for quite a long time. My buddy lent me his manix 2 with bd30p and I really liked it(was bummed I didn't get one myself), it performs like s30v and imo slightly better. Also would like to try 75p, im a sucker for getting knives with different steels, just got my elmax para 2 and im loving it.
 
Rev, a powdered version of BG42 ??? I'm all over it. I love how keen the edge gets on my Millie BG42. If Sal saw fit to do a Manix LW in CTS-B75p, I'd be super in!

I know it's not beyond a possibility that something like that could happen. Some awesome Spydercos have been influenced from the folks here at BF. :) I'd commit to one or two.
 
I think its just a matter of time. IMHO CTS-B75 may be the most logical blade steel in the entire selection of Carpenter steel.
 
I have a Manix in BD-30P that I bought second hand. I found it nearly impossible to get a razor sharp edge with my Sharpmaker. That told me that this is some tough steel and that some diamond rods were in order. I finally got some diamond rods a couple days ago and just today I gave it a fresh back bevel. It needs a little more work but it's getting there.
 
Random revival, I just put my name in on a bd30p manix in the exchange and was researching my purchase, I just really wanted the skeletonized setup. Looks like I'll be happy with the steel too!
 
I'd be down for a Native5 LW in B75P! Just sharpened up my Mule last night, and with the edge Mr. Ankerson put on when he tested it, it was almost too easy getting it back up to screaming!
 
Just some history concerning the two steels in question;
The Sprint Manix 2 in CTS-BD30P was originally to be made with CTS-B75P. When Spyderco got the steel and began to test the heat treatment protocol suggested by the manufacturer, the steel didn't respond as expected. Further communications revealed thet the wrong steel had been shipped. Spyderco decided to go ahead with the steel on hand, for the Sprint run, after using revised heat treatment procedures, with satisfactory results.

;) Many of the long time regulars already knew that the wrong steel went out for the Manix2. The BD30P is an excellent steel and this thread was an appeal to sal to try and find a way to use it in another platform, specifically the Military or the Para2. As for the B75P, it has been used in a very limited way by another manufacturer, but not quite the way Spyderco does it. The Military sprints and Para2 sprints were pretty hot for a while, which is why I threw the idea out there to see if it would stick, but sadly no news indicating it did at this point. Thanks for the recap, it will help the newer folks understand what has been done and why. :thumbup:

I understood it was a happy accident but this helped me with
The details. Love my bd30p Manix! Is b75p hard to acquire/manufacture?
Or is there no market with s30v, CTS-xhp, cts-204p, m390, s90v, s110v, and so many
Others being found in regular production blades!?! So many options by the way...
 
I have owned three Brad Southards in 204P. I have enjoyed playing with this model, even though I rarely carried one. Very recently, I came up with a Brad Southard AVO in CTS-B75P and immediately was blooded by it; a "surprise-nick." It just floats thru 0.002" Yellow Pages...it is the sharpest that I've had by far. I suspect that I will like this steel, given the steel-specs. Although guilty of being a steel-junky, I'm a casual user and not likely to work it very hard at all.
This flipper is a bit thinner in the grip, and lighter than the Spyderco collab, which is fine with me; it carries well. The 3.33" long and thinner blade-stock 0.140" B75P (vs 0.157" Spydie) is welcome. This AVO is a mid-tech, so it costs more, but it reflects the genius of Brad Southard in ways other than my Spydie collaboration.
I'd really like to see Sal use this steel, particularly in a PM2 or perhaps the Caly 3.5, Sage 2 or Sage 3 carbon fiber...all great favorites of mine.

That is my question at this point too. On a similar note I remember all the chatter about Vanax 35 & 75 being super steel, excellent material, etc. then all the talk vanished along with the hopes of actually using the steel in a decent production knife. Only one manufacturer made a knife with Vanax 75. Same manufacturer made a folder with B75P, Spyderco released the Mule in the same steel, but no folder. I would hope the market would be at the very least willing to try it, and I think they are. Oh well, guess we just need to see what happens.
Coincidentally, I did find that I liked BD30P a lot more than S30V. It seems to have an aspect of increased toughness and better edge retention.
 
A Bg-42 Military sprint has already been done which is basically a non-powdered version of CST-B75p.I would venture to guess that we might see PSF-27 knife before another BD30P knife from Spyderco.A laminated S90v model would excite me more than both of the steels in this thread.Both of the Carpenter steels mentioned are excellent from my experiences.
 
I have both Spyderco releases as well as the CTS analog of S90V, 20CP. From what I felt in sharpening it I think the grain structure in CTS-BD30P is smaller than Crucibles S30V. CTS -B75 felt nothing like BG42 on the stone. It is like a different steel. BG42 has/had been my favorite stainless for several years. At rc 62 or above it got a bit chippy when thin. I think the B75 should be able to go higher without getting as chippy due to the grain structure.

I have always seen the graphs say the powder versions of steels at same hardnesses and heat treat are more wear resistant but they do sharpen easier and have seemed like they have had less, not more abrasive wear resistance. I never tested them head to head so I really can't tell if my feelings are imaginary. I felt the same about ingot Cruwear and Powder CPM Cruwear.

They are tougher under impact because of the smaller carbides.

I never saw any CTS - BD30P anywhere else besides the Spyderco run. Even if they only made one heat then somewhere out there is holding a batch. CTSB75 has been used by Strider and ZT as well as Spyderco. Don't know if they made over one heat. It has good potential. It is Vim Var ( extra clean because BG42 is a high speed bearing steel), as well as powder so it's probably fairly expensive but if someone took the opportunity to work up the best heat treat/temper cycle it should be a great EDC steel. Not as wear resistant as S90V/S110V but should be higher edge stability.

So, yes. I'd love to see more CTS B75 especially.

Some would argue that BG-42 and B75P are different enough to be considered cousins rather than twins. A PSF-27 Manix 2, Para2, or Military would be nice. Lamination with S90V seems to be a bit of an odd duck to me, plus from the previous run it was not exactly cost effective compared with historical "sprint runs". In any case, as Joe indicates a head to head comparison would be a cool thing to read about or even try.
