xc75 blade

[ryosuke]

I am interested in fred perrin's knives. He uses xc75 which I have never heard of. I did search but could not find any info. Does anybody know about this steel? Is VG-10 from Spyderco's streetbeat a better steel?

Howdy,
Look at the above references. The first identifies XC75 as the French equivalent of SAE 1074. The second talks about a Fred Perrin knife that the maker stated was made of 1075. So it looks like the Fred Perrin knives are made from ~1075 carbon steel.

1075 is going to have quite different properties than VG10. I'm not certain you can really compare them as they are designed for much different applications. Carbon steel vs. stainless. 1075 is very tough carbon steel so it is much better than VG10 in impact work and easier to sharpen. VG10 is stainless and more brittle than 1075 but will retain an edge longer.

Hope that helps,
Knarf

I think knarfeng summerized all what had to be said.
XC75 is a 0.75% plain carbon carbon steel (I think the "X" means it is better quality - tighter specifications - suitable for cutlery).

Knives by F.Perrin are generally differentially tempered, which means the edge is tempered while the spine is left soft, which adds toughness.
