I'm intrigued with this model but would like some more info before I take the plunge.



Can anyone here give me some more info about the CPM S30V steel used in the blade? Is this a "premium" steel? Why is it so special?



Thanks in advance for any assistance and please excuse my ignorance.

All I know is that it is concidered to be a great blade steel and I have a Military with it,it is the best steel I have tried with maybe the exception of Busses infi steel.

In the CPM process, they start with a completely pre-alloyed molten bath similar to conventional processing. But, instead of pouring the molten metal into an ingot mold to freeze slowly, the metal is poured through a small nozzle and gas atomized to produce a rapidly solidified fine powder.

The powder is screened and filled into steel containers which are evacuated and sealed. The filled containers are then hot-isostatically-pressed (HIP) to achieve 100% density at approximate forging temperatures.

This process is referred to as "Particle Metallurgy" and offers substantial advantages over conventional steels.

CPM S30V was designed for cutlery and offers the best overall combination of hardness, corrosion resistance and wear resistance. It's one of the most respected of the premium steels in use today.

Welcome to the <img src="spyder.gif" width=15 height=15 align=middle border=0>co Forums, CCV! The reason the ATR is so expensive is because it's made with the most state of the art material titanium handle, and 30V steel. These along with having a mono-frame compression lock make this baby expensive to produce! I hate to say it, but I'm surprised it doesn't cost more! RKBA!

Hi CCV, Welcome to the Spyderco forum.

Hey Zrexxer. Very good explanation. I might add the atomized powders are dropped into liquid nitrogen.

Thanks Sal, but credit being due, I swiped that information off Crucible's website <img src="wink.gif" width=15 height=15 align=middle border=0>

This gives me a chance to list the website though, which I forgot to do last night. AND - the best part - Crucible has a picture of a Spyderco Q on their cutlery steels page!

There's a saying, "you can have steel that is easy to sharpen, or a steel that will hold an edge well, but not both".

What makes S30v so special is that at last there is a steel that it is relatively easy to sharpen, and holds a terrific edge.

When I recieved my first S30v steel knife I was very worried about how easy it was to sharpen, I always rate edge golding over ease of sharpening. But over time I have found it requires less sharpening than most steels <img src="smile.gif" width=15 height=15 align=middle border=0>
