Three Rivers Manufacturing (TRM) Knives
Founded in 1997 from a modest Massachusetts kitchen, Halpern Titanium, Inc., the parent company of TRM Knives, has evolved into a premier USA-based knife manufacturing powerhouse. Starting with supplying custom knifemakers, we acquired our first CNC Vertical Machining Center in 1999 to craft precision knife scales for global factories. Today, our state-of-the-art facility boasts 25 CNC machines, two Flow waterjets, Berger flat grinders, Okamoto surface grinders, a Makino wire EDM, and two Swiss turning machines. With a dedicated prototype shop featuring two CNCs for TRM R&D, we create exceptional knives like the TRM Neutron 2, featuring CPM-20CV steel and titanium handles. Committed to quality and innovation, Halpern Titanium delivers unparalleled craftsmanship for EDC enthusiasts and collectors alike.
