Pro-Tech Tactical Response 4 Auto Knife - Blue Aluminum, 4" Stonewash MagnaMax, Button Lock - Made in USA (T4105 F MM Blue)

Heads up: this item will not ship until August 27, 2026.

The Tactical Response 4 is Pro-Tech's full size, hard use automatic. This one comes in a blue feather texture aluminum handle with a 4 inch saber ground blade. It is the biggest of the Tactical Response autos and it is built to work.

The blade is CPM-MagnaMax in a stonewash finish, a high wear steel that keeps an edge and shrugs off moisture. It fires on Pro-Tech's push button, and a steel secondary safety keeps the button from firing while it is in your pocket. There is a glass breaker on the pommel and a blasted deep carry clip for tip down carry.

This is a working and duty knife more than a slim EDC. The 4 inch blade and the secondary safety make it a fit for people who want a large, dependable auto for hard tasks. The feather texture gives you grip even with gloves on.

Pro-Tech builds the Tactical Response line in Placentia, California. This is American made hard use gear, which is right in line with what we stock.
