Pro-Tech T4105-F-MM Feather (MagnaMax, Drop Point, Stonewashed, Aluminum, Black) Automatic Pocket Knife

The Pro-Tech TR-4 T4105 F MM Feather takes the full-size Tactical Response 4 platform and gives it a distinctive upgrade with Pro-Tech’s Feather textured aluminum handle. Built in the USA, this premium automatic features a 4.00-inch MagnaMax drop-point blade with a stonewashed finish, combining a versatile blade profile with a high-performance modern steel. The stonewash helps disguise the minor marks that develop through regular use, making this TR-4 equally at home as a premium EDC, outdoor, or general-purpose cutting tool.

The black 6061 aluminum handle features Pro-Tech’s intricate Feather texture, adding both visual character and additional grip without sacrificing the clean lines of the TR-4. Push-button automatic deployment provides the fast, authoritative action Pro-Tech is known for, while a steel secondary safety switch offers additional security. This model is also equipped with a glass breaker, blasted hardware, and a black long deep-carry pocket clip for convenient right-handed carry.
