I got a Spartan recently and I quite like it:

Cold Steel Spartan, next to Buck Kalinga.
Just recently gave in to my inner mall ninja and bought the Spartan. Showed up in my mailbox yesterday. It's a heavy, solidly built, razor sharp knife. I like it, like the blade shape, like the ergonomics of the Grivory (cold steel for "plastic") handle, like the solidity of the lock, but I probably won't EDC it like I'd planned.
The c-clamp shaped handle feels very secure in a variety of holds, I'm confident there will be no slip cuts. I'm also quite confident the lock will never fail and close on me during any remotely reasonable use of this knife. It's also just small enough to fit into a jeans pocket ok. I don't like the "catch it on your pocket edge" opening stud. Sometimes I don't
want to open my knife like lightning as it comes out of my pocket, and with this knife you have to be careful
not to pop it open with your pants when you whip it out. What I
do like about the big square opening stud is that it gives my thumb or forefinger (depending on grip) a solid platform on which to rest. For a ot of jobs, I tend to place my thumb of first finger on the spine, for better control. The big square platform helps that sort of grip, and enhances the feel of control and stability. One big disappointment is the lock. It's so tight and so bank vault secure that I have a hard time closing the knife. The lock release has to be pressed
way down into the handle, requiring so much pressure I need to use both of my weak girlish hands to do it. This isn't safe, it's just asking for the thing to close on my precious fingers when I put it away. I thought, "oh well, I'll just lube it (two drops of CLP on the pivot and lock surfaces) and open and close it a bunch of times, it will loosen up." That's when it bit me - and I've owned it less than a day.

Barely touched my finger, made a deep clean little cut. Several ZSers recommended more reasonable edc knives. Guess this is my karma for not listening to them.
Nice irony that where I live, the big ole Spartan is legal to carry discreetly, but the same size Buck isn't legal to carry that way, even with a CCW. The Spartan is one of few folders I've owned that I feel might do the work of a similarly sized fixed blade.

ETA: the lock has smoothed out nicely WRT opening and closing, yet stays just as tight and secure in the locked position as ever. This knife is growing on me.
Some people have reported rust issues with he Spartan and with other bead-blast finished knives. I prefer polished or black coated blades myself, not crazy about the bead blast. But I've had no rust issues at all. When I got the knife,
I sprayed a thin layer of Dupont teflon-silicon on the blade and let it dry, then wiped off the excess. I carry this knife in jeans, all day, in the muggy North Carolina heat, thus getting corrosive crotch sweat all over it. Surprised at how well it's held up, rust wise.
