About PSF27:
Spyderco’s nineteenth Mule Team Project installment features PSF27, a tool steel produced using the Spray Forming Process. Spray forming—also known as spray casting or spray deposition—begins by melting an alloy steel in an induction furnace. The molten steel is then poured through a ceramic nozzle and broken up into droplets by an array of gas jets. The droplets are accelerated by the jets to impact onto a collection surface while still in a semi-solid condition. There they build up to form a spray-formed billet, assuming the shape of the substrate surface. The small size and rapid cooling of the droplets minimizes alloy segregation to produce an extremely fine-grained homogenous steel.


PSF27 combines the advantages of the Spray Forming Process with an alloy composition (1.55% carbon, 12.00% chromium, 0.75% molybdenum, 1.00% vanadium) that is basically equivalent to D2 tool steel. The synergy of these alloys and the Spray Forming Process results in a steel that offers increased toughness, wear resistance, crack resistance, and higher hardness. It is also more predictable and dimensionally stable during the heat-treatment process.


What is the Mule Team:
For those of you unfamiliar with our Mule Team Project, it is unique to Spyderco. In-house we call knife samples designed and built for testing and evaluation Mules. We know a healthy percentage of knife users are interested in different blade steels and their performance abilities. Running with that, we released an ongoing Mule Team Project. Several times per year we unveil the same single-piece fixed blade patterned knife in a different and exotic blade steel. This lets steel-obsessed knife knuts test, try and use something normally not offered to the industry. Product runs are limited to 600 – 1000 pieces of each steel type depending on foundry requirements.


Mule Blades are leaf-shaped with a sharpened and finished PlainEdge blade but with an unfinished handle providing a do-it-yourself opportunity. The unfinished handle has a series of holes for attaching custom handle scales or for wrapping with para-cord. Each piece is sold without handle scales or a carry sheath focusing the project on the blade steel. This opens endless creative possibilities for the owner to design their own handle scale and carry options.
 
Seems like it should be good

Seems relatively tough with decent edge holding. I may have to get one since I don't have a Mule yet (kicking myself for missing out on some of them).
 
^^^yeah I'm mad I missed out on the s110v.
I was really hoping the new one would be 10v or something along those lines. But I'm happy with new steels.
 
I would love to see one in something like N690Co or Micromelt PD1 (even though Cruwear is almost identical to PD1).
 
Got one. My wife is not gonna be happy. Been wanting a Mule for a while and it's my first fixed blade.
 
I skipped this round. Is it just me or do others find this steel a little less "interesting" than the last few?

This one is interesting in that we don't know just what it can do yet. There's several flavors of D2 out there and they all seem to be decent knife steels, even if they aren't the last word in edge retention.
 
Heat treating is always the unknown factor in the steel performance.I love the fact that this process may help make
heat treatment easier.
" It is also more predictable and dimensionally stable during the heat-treatment process." quote from SPYDERCO refering to Spray Forming Process.

The interesting thing is that the spray process is supposed to improve toughness. If toughness is improved without reducing edge holding then that is an improvement.

I like that the Mule is used as a test bed for this manufacturing process. This process might be able to be used to change steel properties throughout the billet which would be a benefit to blade steel. I wonder if the process could be used to actually form blades to nearly the final shape and reduce the grinding costs.
 
Wasn't cts-xhp supposed to be a stainless d2? If this works out well then maybe they could do the same spray form process with other steels and really go balls to the wall. If simply spray form process can do that much to d2, then imagine a steel like 204p or something going through the same process. Sounds exciting.
