I've had four different Cold Steel knives fail so far. And everyone has been a fixed blade so far. The first was a True-Flight throwing knife. The seventh throw I made with it , it snapped in half at the handle/blade transition. There was an obvious flaw in the steel where it broke, clearly visible. I took pics, and emailed them to Cold Steel several times, never got a response at all.
The second was a Carbon V Trailmaster Bowie, it developed a crack in the edge about a third of the way down the blade. The crack was about half an inch long, I'm sure the entire blade would have snapped had I continued using it. This knife never did anything harder than trim saplings about an inch thick . Again, no responses to warranty questions.
The next was a Carbon V Kukri, it had a quarter sized chip break out of the blade while chopping through a 3/4 rotten and punky spruce log, about 6 inches in diameter. Not very impressive, considering a $10 thrift store machete finished the job without missing a beat.
The last one that's failed was a Spike, it got dropped accidentally, and a full quarter inch of the tip just bent to a 45 degree angle. That's how soft the steel was , might was well have been mild steel.
Never once have I gotten a return email from Cold Steel about warranty, and even phone calls just end with promises that I will get a call back, and nothing happens. They'll never get any more of my money!
