Upcoming MT32P (SRS13/SUS405) discussion thread

#1

Post by Araignee »

As announced in Reveal 9, the upcoming MT32P Mule Team will be fitted with SRS13/SUS405 steel.

Below is the description from the prospectus :
Spyderco’s unique Mule Team Series elevates the concept of a “mule” in-house test knife by allowing our customers to join in the process. Offered without handles or sheaths, our Mule Team blades are also popular “kit” blades for aspiring knifemakers and hobbyists.

Our 32nd Mule Team installment features laminated san mai (three-layer) construction using a central core of SRS13 clad between layers of SUS405. SRS13 is a unique powder metallurgy martensitic stainless steel enriched with molybdenum, vanadium, and tungsten that is the steel of choice for many premiumgrade Japanese kitchen knives. SUS405 is a ferritic stainless steel that provides greater overall blade strength and toughness while allowing the hard SRS13 core to excel at cutting performance.

So I wondered about these two particular steels and why they were coupled in such a way, and found this post from Bladeforums :
Japanese kitchen knives are made of very thin cutting core (typically less than 1 mm thickness) clad in softer stainless steel. There are two reasons this.
  • For ease of putting initial bevel when the knives are made. Cutting cores are typically made of harder metals, thus they cause more wear and tear on the tools used to grind them. To minimize wear and tear, cutting cores are made very thin (typically less than a 1 mm), and clad in softer stainless steels such as SUS405 or SUS410 for added strength (so the knife doesn't snap in two) and protection (against corrosion).
  • For ease of sharpening. Most people use their kitchen knives much more often than their sporting knives. For this reason, kitchen knives will typically require sharpening more frequently. Thinner core means easier sharpening and their sharpening stones will be subjected to less wear and tear.
Hopefully knowledgeable people will chime in and provide their opinion on this explanation.

A good opportunity to have a high end kitchen mule. I don’t know enough to get excited about this steel and also because of my current love of ZDP-189.

Oh yeah ! I hope it doesn't come before February or March though. I'm not broke but this would bring me closer to that state :nerd
:respect In the collection :respect : Lots of different steels, in lots of different (and same) Spydercos.

$75 according to the pricing guide. Since this is #32, I assume this is from one of the steel orders that was made before the market went crazy and the quantities were increased?

This steel was new to me. After a quick search I found an explination Larrin made in the comments on his article "Testing the Edge Retention of 48 Knife Steels":

SRS-15/SRS-13 are basically PM D2 steels with increasing alloy additions for more “hot hardness” and wear resistance. I wouldn’t really compare them to AEB-L as they have much more carbide in them for more wear resistance and lower toughness.

I think this will be the first "clad" mule team. Was super blue solid or clad?

I need to slow down when flipping the catalog. Totally missed this. I thought I was safe / going to save money this round. But I do want this.

I’m almost disappointed in myself that this mule has me feeling very ambivalent. Having the B70P (which is similar enough in chemistry), as well as magnacut, this one doesn’t call to me.

Maybe I’ll try for it. If not, I suppose it’ll be nice to save a little money; I just didn’t expect this of myself for future mules.
Have: old S30V Native, HAP40 Endura, ZDP DF2, S110V Manix LW, Cru-wear Para 3, SE H1 DF2, S90V Native 5, K390 Urban, SE Pac Salt, P.I.T.S., XHP Manix LW, SB Caly 3, B70P, PMA11, K03, Kapara, REX 45 Military, 154CM Manix LW, Swick, AEB-L Urban, KC Cruwear Manix, M390 PM2, Mantra 2, CruCarta Shaman, M390 Manix, K390 Police 4, S90V Manix LW, Rex 45 Manix LW, 20CV Manix, Rex 45 Lil’Native, Shaman, C208GP, Cruwear Manix, Cruwear Manix, M4 Chief, Z-max!!!

Want: SPY27, K490, Swick 5

This could be really interesting. Hopefully it's obscure enough that the demand will not be huge.

The Cobalt Special #9 was a clad Mule from back in the day.

I have only heard about this alloy in a video from Shawn. Believe he described it as “stainless cru-wear”.

Does anyone here have experience with it in kitchen cutlery?

Count me in! Honestly Sal could make a MuleTeam of glitter Damascus from 1980's prom dresses and I'd still want one.

I'm interested but not familiar. I've seen a number of high quality Japanese chef's knives in this steel just looking it up now, but I haven't found much int he way of comparisons. I have read that SRS13 compares to Super Gold 2, with less chippiness, so it sounds like a nice mix.

I'm not one who needs every mule, so there will be at least one more available. Still, I'm happy Spyderco is still finding interesting steels for the Mule Team project.

Fingers crossed for the sheaths to be back in stock for this release -- I panic bought my Magnacut Mule (fearing it would run out of stock) as soon as the site started working again, so would love to be able to pick up a couple leather or kydex sheaths.
