The CobraTec Large CTK-1 OTF Stonewash is CobraTec’s workhorse out-the-front knife. It runs a D2 steel tanto blade with no serrations. D2 is a hard-use tool steel. That means it holds an edge through cardboard, strapping, and jobsite abuse. Plus, the strong tanto point stands up to hard tip work.

Press the thumb slide and the blade fires out the front. Then pull it back and it stows just as fast. Because it is dual-action, one thumb does all the work. Also, CobraTec machines the 5.75″ handle from tough aluminum alloy in Stonewash.

On top of that, you get a glass breaker on the tail. The pocket clip swaps to either side, so left-hand carry is easy. A nylon sheath comes in the box as well. In short, the CobraTec Large CTK-1 OTF Stonewash is built for real everyday carry.

Not only is this a 5 star review, I am going to throw 5 more ⭐️⭐️⭐️⭐️⭐️ making it a 10 star review ! Scott is such a nice guy. In this show I bought flashlight and then at the end of the show I got picked for the buyers givvy at the end of the show. Scott knew that I really wanted the full size pen made by Olight and he gave me the option to upgrade ( for free ) the prize. He told me to pick a hand and I picked his left and wow it was the one that I wanted and the other hand was a knife with a leather sheath. Now I don’t know if the pen was in his left hand under the table or if he switched it to his left hand because he knew that was what I truly wanted. Regardless I ended up getting what I was wanting so THANK YOU Scott you are awesome !!! During the same show he ordered a knife that he didn’t have that I wanted because it would save me some money if he purchased it instead of me just spending more buying it from the manufacture. Now all I have to do is hope that no one runs me up.

The knives I bought are Extremely nice and the prices of them were Great - The O Clip light is very nice and bright for its size - The mini pen and pencil is smaller than it looks. I have very big hands so I will probably end up giving it to my wife. - The O light i3T - 2 Is a nice color but it is extremely dim for the advances in flashlight technology that other light makers are utilizing. I have a Nebo flashlight about the same size that puts out 3 times the light that the i3T-2 does. - Overall not a bad deal. - Shipping went out same day or early next day - Package arrival time from purchase was remarkable - Thank You
