So to be fair, my point in "compares" is simply blade steel, heat treat, functional cutting. Obviously CRK is known for their super smooth almost hydraulic opening and vault like "Kerchunk" lock up sound. I've owned several, but have to admit until they started offering magncut, I got rid of most of them because there were just so many options at half the price or less that had far better edge retaining steels. I could put a variety of knives in my pocket that cost half as much and held an edge much longer. Offering a fairly high hardness magnacut option of course changed that equation. In fact I'll probably put in new blade requests to make most of my old CRK's (which at this point is only 3) magnacut bladed.
My point was for a long long time your only option with a CRK folder was soft heat treated s30/s35 (soft even for s30/35 options from other manufacturers). The last few years it's been pretty easy to get s30/s35 blade knives in and under the $100 range with heat treat that were higher than what CRK was doing, and higher end steels (s90v, 20cv, M390, etc.) under $250. Where they better overall knives in fit/finish than a CRK, with titanium handles, of course not, but here again cutting is what a knife's function is and s90v is going to cut circles around soft s30v for edge retention, and something like 3v is going to be similar edge retention with much more durability. Now you can go either way on that right, CRK's position back in the day was that a softer HT on s30/35 made it easier to maintain in the field by being faster/easier to touch up and sharpen, and he was not wrong. Though I'd wager the vast majority of CRK folders sold are not getting beat up in the field and sharpened on flat river rocks

CRK also had a vested interest after all he was directly involved in the making of s30/35/45 steels with Crucible. The biggest advantage to those steels as opposed to other options were not that they were amazing cutting performance, but they were very easy (cheap) to machine/grind compared to other options. Don't get me wrong those are all very good steels, we're lucky to have them, but even in 2015 s30/35 was just middle of the road for what was available.
Striker had some nice fixed blades, and their folders were iconic back in the day, but I hated the handle shape, I think I still have a SMF somewhere where I ground the square hump on the handle rounded and reprofiled the blade geo. The one thing Strider did well back in the day, the same for Microtech is they had an amazing heat treat on s30 and ATS34 compared to other options. At some point the mid-tech craze started and it was basically just a way to get buyers to drop $400-500 on what was really just a production knife with better CNC'd parts.
The PM2 is still one of my favorite knives, I keep coming back to it. It's light, has a good handle, a lockup you can't accidentally release, it's not expensive and you can get it in a wide variety of steels. Plus it bucks the tacticool trend of folding knives having much too thick of blades for general everyday cutting. It also has really good grip with the peel ply G10. So many knives today are using smooth G10, or smooth aluminum/Ti handles, and they just don't have good grip if your hands are wet etc.
Elmax is a great steel, I really think it went underrated. I had an old ZT in elmax probably a 561. ZT back then really was turning out a lot of great designs.
With knives over the decades I've owned a ridiculous number of them, but like guns I've scaled a lot of them back to keep a few I really like/use. 90% of the time my Zaan or a PM2 end up in my pocket, but I also really like the Spyderco Smock, BM 940, BM Rift. In newer stuff for a smaller knife I'm a fan of the Hogue Deka's and the Demko AD20.5's. If CRK had done M390/s90v/20cv blades my Zaan might never leave my pocket, and it may not again if I ever get around to getting on the list for a magnacut blade for it. I don't currently own one, but another knife I really loved for being similar to CRK in vault like lock up and almost hydraulic like opening was Les George VECP, but the blade shape didn't really fit my everyday cutting needs, I'm not a fan of a lot of "belly" in my pocket folders.
Like so many things we're really lucky with the options we have now in knives. I have a couple very old Benchmades from the 90's (975 and 910) and every once and awhile I pull them out and mess with them, and at that time those knives were cutting edge, top of the heap for factory options, and comparing them to Benchmade's etc. today the difference in fit and finish and lock strength etc. is super obvious. The stuff today is vastly superior, and those old BM's are more the quality level you see on like $50-75 Civivi type knives.
