I will admit for as hard as it was to sharpen>> to be truthful it was a "MONSTER" to sharpen in plain edge :eek: But I still use two of the older full Spyderedged models in 440V and it's truly one of my all time favorite blade steels for Spyderedges IMO.sal wrote: ↑Thu Jun 14, 2018 10:15 amHi Shawn,
Spyderco was the first production company to use Crucibles particle metallurgy in production knives. I personally went to Crucible with crew to begin the project in the mid 90's. We began with S60V while is was still being called CPM 440V. We had no problem getting it hard, but in a hi 50's to low 60's it was so brittle that it would crack if dropped on concrete. We continue to experiment until we reached the conclusion that 55/56 worked best for the steel in knife blades. In the end, we dropped it. It was too hard to sharpen for customers, though edge retention was good. I don't think we would use it again.

Being that most of it only tested out at 55 to 56 on the Rockwell scale probably explains to me why it was such a good blade steel for Spyderedges. I hope to get my hands on one of the older 440V, full SE Military models again some day. That was a true beast of a serrated blade in 440V.
I guess what I'm trying to say is that if you all ever get anymore 440V you can at least use it in Spyderedged blades. I rank it along with ATS-55 and AUS-8 as being my top 3 favorite blade steels for Spyderedges.
I just purchased an old Golden-made Native in 440V SE due to this reply and your love of 440V SE in some old threads. I hope it lives up to the hype!
