CobraTec zinc alloy knives are purpose-built to be among the toughest high-quality automatic knives you can buy.
This claim starts with the use of 440C stainless steel blades. They have a higher carbon content than standard 440 stainless, so they're even tougher than the 440 stainless we are accustomed to in a quality knife.
But, it's more than just a tough blade. The handles are tough too. They are made of zinc alloy, so they can take all the same abuse that the blade can take.
Also, everything on the inside is stainless steel. From the detents that hold the blade inside and outside to the carrier, to the spring - all stainless steel.
Additionally, the glass break on the end is a steel ball bearing, instead of a sharpened piece of metal that may blunt when you try to use it. The ball bearing is excellent at breaking a car window for emergency escape and/or rescue. We have that on the word of multiple first responders who have used theirs in the field.
Also, the belt clip is steel. It holds it's shape and strength very well.
Lastly, the switch is solid metal. Some are hollow. Some are even plastic. With CobraTec the switch is solid metal. Far less likely to break if it drops on the switch.
Every aspect of these knives are purpose-built to be the toughest automatic knives.
They do of course carry a lifetime warranty, as you would expect from a knife built in Texas to be the toughest. Best of all, they actually stand behind the warranty, as you would expect from a Texas company. You don’t have to jump through hoops to get them to stand behind their products.
Nor will you have to wait a long time to get it back. They have a one day turn around policy.
As of this writing, we ourselves have put 4,500 of these knives on the street. We can attest to all of these claims, and we have tons of client validation. It’s a good company. These are good knives.
Our number one phone call is, “showed my buddy my knife, he wants one too!”.
