The Pro-Tech TR-3 is from the Tactical Response series, but is also one of the best EDC knives in the Pro-Tech lineup. The knife has a utilitarian drop point blade with a swedge and a slicy belly. The handle is contoured for secure grip in even a forward or reverse grip. Be it for self defense or slicing an apple, the TR-3 is here for you!
