      Hard to find this badass

      Posted by Eric Gribbell on 31st Dec 2025

      I'm so fortunate to get this one, as the fire pattern on the handle is so unique! Everything about this is pure Protech. Magnacut blade and a little more heft to the knife than some of the smaller TR models. Persoanlly I like this size quite a bit
