    ProTech T4 - T4101 in Green

    Posted by Jeb Hood on 28th Sep 2026

    I have made a few changes to mine but for the most part this knife is ready right from the box. The finish texture on the blade is next level guys, just love the finish on this blade. I also love the added glass breaker and slot for my lanyard. That's next level stuff from? Just a hole in the scales, that is usually to small of a hole anyway. The finger grooves sculpted in the scales are awesome as well as the jimping on the spine of the knife for your thumb. This is an area I added more jimping to the spine of the blade right in front of the pivot point by the tang. You find yourself needing to choke up on the blade for some fine detail work or need way more effort to cut through something, this was a must have for me. I also bent the tip of the pocket clip out to get it over the pocket started easier. Some guys like to stretch the clip out for this, but I want my clip really tight on the pocket, but just by bending the lifted point of the clip, it gets started over the pants pocket more easy and you just shove it on the lip of the pocket. I do this to every one of my pocket Knives. All screws where found torqued tight and ready. The bevel on the cutting edge of the MagnaMax steel found somewhere between 19 and 20 dps... I re-profiled mine to 15 dps on my Tormek T8 and finished to a polished finish with a 4000 grit Japanese Waterstone. The MagnaMax steel does take an edge too. This blade is razor sharp, literally. A razor has nothing over this knife. ProTech has added a push button lockout switch, realize addition. My 5" Brend has come open inside my pocket and if you keep your knives like all mine, that is not a good thing lol... The speed in which this blade opens is good, fast and strong. Much improved over my 5" Brend... I have only had the knife a week, but its a keeper, may have to get another in the black as well. If I had to wish for anything added to this knife I need help doing, it would definitely be for ProTech to make this knife in the burnt bronze finish color.
