Well, I know that a couple of others have already reviewed this knife, but I thought I'd throw in my 2 cents. I bought this one for my nephew, who is starting to be interested in knives, but needs to be saved from an apparent love of S&W knives. The specs are:
* Blade: Length: 3.75" (95 mm)
* Thickness: 0.12" (3.0 mm)
* Steel: 8Cr14MoV, 58-59 HRC
* Closed: Handle length: 4.88" (124 mm)
* Open: Overall length: 8.50" (216 mm)
* Weight: 3.6 oz. (102 g)

My first impression is that this is a very, very attractive knife. I like the combo of the blue/black micarta and the blue liners. Fit and finish was good. The scales were finished very well and everything fit well with everything else. The blade was not perfectly centered, but it wasn't rubbing on the liner either. I think that a small adjustment to the pivot will take care of it. The opening action is extremely smooth... it swings open just like my Mcusta, which is one of my smoothest opening knives. The flipper works very well, which is good since that is the only way to open it. The liner lock seems thin. It engages about halfway across the tang with an authoritative click, but man it looks thin. There is zero play in the blade in any direction.
The clip is right handed tip down only, with no other mounting options. Due to the contour of the micarta, I doubt you could tap it for any other position. The knife was shaving sharp out of the box with a nicely finished blade.

For the price (~$32) I am impressed with this knife. So much so that I am keeping it, and ordering another for my nephew. The only concern for me really is the thin liner, and we'll see how I feel about that after some use. Otherwise, it is an attractive, hand-filling knife that is pretty darned comfy to use.

I like mine quite a bit, because of its sinuous shape I call it "my tactical laguiole" :)
Perhaps the most attractive current CRKT.
I am also curious how the liner lock will hold up, I do expect to be sufficient when used for pure cutting tasks.
 
Today I picked up the other McGinnis knife, the Tuition. I will be doing a review on it in the next day. I also have some concerns about the liner lock which appears to be almost identical to the Summa, but I have some thoughts on it that might be worthy of consideration. I suspect that I will also be adding the Summa to my stable.
 
The Summa is a great folder, CRKT did a great job. :thumbup:

Performed well on various materials, eg. on cardboard. :thumbup:

Does the finish of the clip match the blue of the liners?

Just bought a Summa today.
 
That's a pretty knife.

My M16-EDC has the same type of liner lock - it has never failed.
In fact, sometimes it gets wedged in there so tight that it's hard to unlock.
(Of course the M16 also has that little liner lock locker, which sometimes catches me by surprise...)

It is a pretty knife indeed. After carrying it a bit I do feel better about the lock. It seems to be solid despite appearances, and the knife is a heck of a slicer. Still happy.
 
I've had my Summa (black partially serrated blade) for a while and I've had no issues with the liner lock. I did pick up a second Tuition (now have both smooth and partially serrated) and the liner lock on it was much more firm than on my first one. I took the first one apart and bent the liner lock just a bit. If you lay the liner firmly down on a flat surface and bend the lock portion upward just a bit it's often just enough. The lock is now just a firm as the second one that one was fine from the start. I know, it probably voids the warranty, but it's an easy fix if you're carfeful. These aren't heavy duty knives and I think the liner locks will be more than adequate. Same with my BM Mini Dejavoo (which is notorious for its liner lock) after the same fix.

BTW, Gerry McGinnis has some new CRKT knives coming out for 2010 and they look very nice. At 19 years old he has quite a future. Good to see it.
 
Anyone have issues with the micarta being overly slippery, or is that not a concern?

Its not a great knife to try and use when your hands are covered in gear lube, but even then it didn't slip out of my hands, my index finger was stopped by the flipper/guard.


I'm looking at mine and maybe they changed something, but my liner isn't thin, it looks like its the same thickness as the liner on my tenacious, but it does have the spot around the jimping angled a bit which makes it look thin. Either way, no failure yet.

The serrations are ground too thin, just like on every CRKT with the Veff serrations...Get the PE version
