I'm looking for a nice present to a culinary friend. I know these are very rare and there's other knives out there but this is one that I would very much like to get her. Any suggestions on how to get hold of one?
 
Hello,

In "The Spyderco Story" book it says the knife was marketed (says here it was designed by a Brooklyn Rabbi) as the "Collif", but that many people have never heard of it (myself included), I was interested enough to pull the book off the shelf of my library to check it out. It was given the designation K10, I'm a bit confused as to whether it was actually manufactured. I'm sure someone far, far more learned in Spyderlore can give you a better idea than me, but it was a very interesting question.

Cheers,

Rob
 
It was made but you hardly see them.
 
madhaha, both went on Ebay 2 months ago or so. They did go to about $75 IIRC.
I snagged the picture of Ebay and had it photoshopped by Robert to match the other pictures in my list. The lines on the blades are from scanner interference as was said by the original seller. The blade has a standard finish.

MRS-30. 1.15 carbon. Made for Kosher butchering of chickens.

We made one run many years ago.

$75? Gone?

I think I'm going to cry. I'm guessing there won't ever be another run because of the size of the obvious market... Its a shame because they must be amazing knives.

Ted: I've seem your site. Its a great resource. Keep up the good work.

After some heavy digging I've picked up a couple of references to it in old BF threads, but I'm guessing Sal's back supply is long gone (or retained for his own museum and replacement parts) and it'd be unreasonable to demand one. Any leads on where ted's knives have got to?

Some years ago I researched Kosher slaughter, with my primary interest in the humaneness of the process.
The top knife looks very much like the group of knives I saw, which rabbis would use for slaughtering various animals.
Apparently, they choose the steel, blade shape and edge geometry for the purposes of the animal not feeling the cut and thus not suffering.
In this regard, would Sal please comment on the MRS-30?

madhaha, they were not mine and I was not the seller nor the buyer

I did send a question on Ebay to the seller (or buyer - can't remember) however to ask for better pictures. I didn't get a reply on that but I'll try to dig up their ID's so that you can try for yourself.

Hi Ken,

MRS-30 is a high carbon stainless steel (C=112, Ch=14, Va=4.0) steel that was propietery to several makers. I believe it was made by Daido. Very highly refined steel.

Rabbi Yurman is New York was regrinding our Sanotku kitchen knife (MBS-26) into "Challifs". I suggested making a custom run, which we did. It makes a beautiful useful kitchen knife as it was. Rabbi Yurman had the edges reground to .1 mm thick. He likes a very sharp edge. MBS-26 wasn't available when we began production, so re replaced the MBS-26 (.85-1.0 carbon) with the higher carbon MRS-30 thinking it would be superior because of the higher carbon content. Also made by the same foundry so purity was assured.

As it turned out, Rabbi Yurman said he was having a problem with the edge breaking out. It seems that the carbon content was too high for the thickness of the reground edge. The secondary carbides were breaking out at the edge. Magna flux testing under a microscope revealed the problem. A great steel for "normal" useage, but the razor thin grind was too thin to support the secondary carbides. A good lesson for me and a good argument for powdered metals.

And who more learned than the Honcho himself. Thanks Sal, I allways have to remember "don't believe everything ya read"

Cheers,

Odin, guide my sword to eternal victory!!!!!
 
A fascinating answer from Sal.
Thanks.

For kitchen knives, then, does Sal prefer MBS-26 or the powdered steels?
I believe Spyderco presently uses MBS-26 for its kitchen line of knives, so perhaps that answers my question.
 
My first choice for kitchen knives is still MBS-26.

Although I do use several in MRS-30 made by Masahiro and I have a few Murray CArter pieces that I also enjoy.
