Big, sturdy, heavy. Sharp.
Got this knife a few days ago. Serrated version. Full flat grind, gray handle. Really heavy, but I like that in a knife. Super sharp, comes really stiff but gets better after some use. I love the handle. It fits my hand perfectly. Build quality feels amazing. Wave opener makes it immediately deploy right out of your pocket which is really easy opening. Overall 10/10 great knife so far.

Like having a mini-machete in your pocket!!
I have a small banana farm in Hawaii and I was looking for the largest pocket knife I could find. This knife is amazing. I was able to process my banana plants with ease; it was truly like having a mini-machete in my pocket. Highly recommended!!

The media could not be loaded. There is nothing to dislike about this knife.if you have small hands dont get this knife.definitly worth the money,very strong in its construction, solid blade. I really love the handle ,helps keeps the knife in your hand while wielding it in defense and striking. The only thing wrong was they sent the wrong color.Its says black,i got gray.

Sharp, Sturdy, Serrated
Love Cold Steel, love serrated blades. I give this 4 out of 5, the missing star is for the sheer weight of this monster. It's a stretch to consider this a pocket knife. That being said, the sharpness and balance of this blade is excellent. If I could only have a single knife in the wild, might be this one. Oh, I do live in the wilderness, and I won't be returning this one.

Wanted a serrated blade, went with this one.
I had the regular spartan for a short while, and fell in love with it. I decided to get a fully serrated blade , and figured cold steel would be the best bang for the buck. I considered the talon, figured I had a ways to go before I’d be comfortable with the Tiger Claw, and while I love my voyager xl vaquero, I wanted something that will wave.Honestly I’d been happy with another black handled stone wash blade, but the handle came grey and the blade mirrored. A win win!After needing a 3rd party clip for my SR1, and how happy that has made me, might shop for some for my Spartans .
