So I'm wondering about steel again...

The subject of knife steels really fascinates me. I'm not really sure why, but I just really like to learn about them. I've been looking at various steels, their compositions, and all that, but it doesn't really give me a good understanding on how they compare to each other, their uses, etc. I'm really interested in some of the following steels as they seem to be very high quality, but I can't find a lot of knives that offer them. Can anyone list the uses, characteristics and knives that some of these steels can be found in?

Also, if I was to ever want browse knives categorized by steel used, is there a good website for doing that? I'd like to try some of these for myself some day.

This is what I know about them so far...

H1 - "True Stainless" steel that apparently doesn't rust. I've only seen it available in Spyderco's "Atlantic Salt". I don't know anything more about it.
M2 - High-speed tool steel, don't know much about its characteristics other than its used for high speed cutting, only know of a few Benchmade and Bark River models that use it and apparently it's very tough stuff.
M4 -- Spyerco Gayle Bradley uses this, and according to them "six times the wear resistance of D2 at the same hardness"
M390 -- I don't know anything about this one except it seems to be able to be hardened quite a bit, and is available in Benchmade's 755 MPR and knifework's 710 exclusive
3V/9V/10V - A line of Crucible steels that are apparently very tough and wear resistant. Don't know much else, or any knives that have them.
S60V/S90/S125V -- Apparently versions of S30V with higher percentages of carbon and vanadium. Most reputations I've seen for them is wear resistance, once again I don't know of any knives that use them.
INFI -- I know virtually nothing about this except that it's very tough and used for "chopping" applications.

Any that I left out that others can think of? From what I've been able to find so far M4 and M390 don't seem to be so hard to find, where as lot of offerings of M2 that I've seen are just in knives I have no need for and probably couldn't afford.

I'll probably save up for the Gayle Bradley to try out M4. It looks like a pretty nice knife anyway. Any other recommendations of knife to try for each steel? Or maybe some more steel/knife recommendations I missed?

P.S.
There's no real practical reason behind this, I'm just curious about these steels, and I can always resell the knives later if I don't like them.

I am in the same boat, I dont know why either. Also looks like you are missing VG-10 from your list I really want a knife with this steel I am eyeing the Spyderco Endura 4 in blue. From what I have read and seen on the net its a very nice steel for EDC. I am waiting on a Spyderco Paramilitary 2 it has CPM-S30V. From the very little research I have done Spyderco seems like a good choice for the money and for me.

Well, right now I'm trying to find more info on steels that I haven't heard a lot about. I've heard tons on ZDP-189 and VG10 from their Spyderco offerings, otherwise they would have been up on the list as well--but I plan on getting a ZDP-189 blade after the Gayle Bradley.
 
VG10 is a very good steel-high corrosion resistance, easy to sharpen and polish up, holds a razor edge pretty long.

As for M4 it is tough, wear-resistant and quite easy to sharpen. Despite Crucible rating it as more resistant than S30V I prefer to sharpen the M4, not sure how much of this is due to the GB's thinner edge though. It just seems to burr less and polish up more nicely.

Both spyderco and Benchmade have browsing by steel if I am not mistaken.

I have it for the knives I've owned:
Custom Knives By Steel
Kitchen knives by steel
Folders by steel
Fixed blades by steel

Any that I left out that others can think of?
Yeah, few hundred more in knife steel chart :)
