Everyone reading this has either had some variant of a folding knife or at the very least has seen them at flea markets, pawn shops, sporting goods stores or other retail outlets. Let's face it. Some are absolute junk. Others are decent and sometimes a good buy for the dollar. Still, others are very good. However, Cold Steel has it all over the competition. Again, no compromise. Here's why:
The cornerstone of the Tri-Ad's™ strength, among other subtle refinements, is the inclusion of a new "stop pin" which re-distributes the load of vertical positive and negative pressures on the lock.
The stop pin receives all positive pressure (pressure on the cutting edge) and transfers it into the handle frame and liners where it can be more effectively absorbed. Negative pressures on the lock produced, for example, by prying, digging, piercing or even abusive spine whacks are redistributed because the stop pin receives the forward pressure from the rocker and transfers it into the liners protecting the rocker and its pivot from failing.
Self Adjusting...
Finally, outside of keeping the lock free from the buildup of pocket lint in the mechanism, the Tri-Ad lock requires very little maintenance. It's designed to be self adjusting, in the sense that, over time as parts begin to wear, the Tri-Ad's™ design will allow it to adapt so the locking bar always wedges deeper in the lock channel between the stop pin and the shoulder of the precision cut tang notch. This feature allows for a very safe and secure lock-up.
It is why you'll see demonstrations of Cold Steel Folding knives capable of withstanding 600 lbs. of weight hung off the end off the handle while the knife itself is locked in a vise and then come out of it unscathed. You'll see videos of knives like the Legendary Cold Steel Espada doing things things no other folding knife but one manufactured by Cold Steel could come close to.
