Pro-Tech TR-4 - Black Aluminum - Black DLC MagnaMax Blade

MagnaMax Button Lock Automatic with Aluminum Handles

The Pro-Tech TR-4 is a full-size automatic folder built for users who need fast, one-hand deployment. It carries a glass breaker tip and a steel secondary safety switch to prevent accidental firing in the pocket, making it a serious option for those who rely on their gear working right the first time.

Blade

The 4" drop point blade is made from MagnaMax steel with a black DLC coating. MagnaMax is a premium high-performance steel that delivers strong edge retention, good toughness, and solid corrosion resistance, making it well suited for a hard-use automatic. The DLC finish adds extra surface hardness and cuts glare while further protecting against corrosion.

Handle

The handle is machined black aluminum, chosen for its light weight and durability compared to steel. Blasted hardware adds a contrasting texture against the smooth anodized finish. At 5.3oz, the TR-4 carries substantial without feeling heavy in the pocket.

Carry

This is a button lock automatic - pressing the button fires the blade open instantly, and the same button releases the lock for closing. A steel secondary safety switch adds a manual block against accidental deployment. The black long deep-carry clip is set up for right-hand, tip-up carry only, keeping the knife low and discreet in the pocket.

Made in the USA.
