Good spyderco blade steels

He asked what are the pros and cons of the different steels Spyderco uses.

Oh ya i didnt catch that. :)

Well I can only comment on 2 of the steels they use. VG 10 and CPM S30 V.
In my experiences with these 2 steels, the S30V holds an edge longer than the VG10 but is harder to sharpen. But not by much. I haven't had any issues with chipping or rust. They both take razor sharp edges and a nice thin flat ground knife like the Spyderco Sage cuts like a laser.

You cant really go wrong with Spyderco
 
Two pages an no one has offered a response that actually answers the OP's question.

He asked what are the pros and cons of the different steels Spyderco uses.

I think he was looking some something along the lines of what are the performance differences between VG-10, S30V, and 154CM. Maybe a couple others.
Differences like wear resistance, brittleness, rust resistance etc.

spyderco does large amounts of testing and based on that research they match steels for what a specific knife is intended for. i'll give you an example: the spyderco salt series. those knives are intended for salt water/harsh environments, so they use H1 (which won't rust). i'll give you another example: the spyderco gayle bradley. gayle is an expert knife maker/champion in bladesports world cutting competition, so spyderco uses M4 for the knife blade.

the most important thing is that spyderco takes the time/money to match blade steels for intended use. we all have our steel preferences, but i doubt you will find a spyderco that doesn't deliver on what it was designed for. you'll be hard pressed to find a knife company using as many or more different steels than spyderco.
 
Spyderco is one of the companies that pushes the limits bringing to market new and better steels and I take my hat off to Sal Glesser for that. :)

The other one is Kershaw (Yeah Thomas I didn't forget about you). :)

Now Strider is starting to use some very high end steels also so in all it's a great time to be a steel junky. :D
