I've always been satisfied with my Cold Steel knives. The folders lock up tight, and the fixed blades, well, they stay fixed
. The edges come nicely sharpened with a good working edge that stays sharp for a considerable amount of time. I've never had a problem with corrosion or rust being a problem, but I always wipe my blades down with Birchwood-Casey Sheath to keep them protected. I don't use my knives for screwdivers, I use the proper tool. I don't use them for prybars, I use prybars instead. I don't use them for axes, saws or mini-machetes. I use all my knives for the one purpose they are meant for, and that is for cutting things, and in that respect, they perform flawlessly. I am tempted to try some torture tests on them though, just for chuckles. But not until I can afford replacements, because honestly, I'm doubtful as to the amount of abuse that they could take.
