Neutron 2 Framelock - Titanium Radial Handle - 20CV Blade

In 1997, Les and Marianne Halpern launched Custom Knife Supply from their Massachusetts kitchen, armed with $2,000 in titanium scraps, 10,000 screws, and a bold idea. That kitchen project eventually grew into Halpern Titanium, one of the most trusted manufacturers of knife parts in the industry, producing millions of precision parts for top brands. In 2014, they stepped into the spotlight with their own knife brand: Three Rivers Manufacturing (TRM). Thoughtfully designed, American-made, and built for everyday use, TRM’s knives like the Viator, Neutron, and Atom quickly became cult favorites. A community formed. Fans lined up for drops and swapped scales. Today, TRM Knives is an evolution with the same ownership, same quality, same U.S.-made promise — a brand built on quality, trust, and a fiercely loyal community that helped shape it. When you carry a TRM knife, you’re part of the family.
