If you are looking for a good affordable knife that can take a lickin, cold steel can provide it. Although CRSK puts out some awsom knives that do hold an edge. The top knife in this picture is a real work horse. I never liked a serrated blade until this knife. My back yard had old anchors and stuff, with different types of rope. This knife cut rope, cardboard, carpet, and one finger better than any knife I ever owned (although my Buck Special, after being sharpened on a lansky did seem to enter my leg rather effortlessly and with no intent on stopping).
The Cold Steel Pro Lite comes serrated and non. The serrated is just a wonderful knife, heck, it can pass as a small spade. I've had it for 7 years, used the heck out of it, and it doesn't need sharpening. It's still scary.
anyway, thats my opinion.
