TRM builds thin slicers, not thick tanks. While other companies chase blade thickness and overbuilt designs, TRM went the opposite direction—lightweight folders with 0.090" blade stock that disappear in your pocket but deliver exceptional cutting performance. Made entirely in Three Rivers, Massachusetts, using MagnaCut or CPM 20CV steel, these knives prioritize what actually matters for daily carry: slim profiles, razor-sharp edges, and materials that last.
Why are TRM knives so hard to find?
TRM is a small operation run by Les and Marianne Halpern. Every knife is assembled by hand in their Massachusetts shop, and they refuse to outsource or compromise quality for quantity. When new batches drop on their website, they typically sell out in minutes. The wait is frustrating but worth it—you're getting a knife that's genuinely small-batch American manufacturing, not marketing speak.
Neutron or Atom—which should I choose?
The Neutron (and Neutron 2) sports a 3" blade in a 4" handle, making it one of the best sub-$200 compact EDC options available. The Atom bumps up to a 3.45" blade for those wanting more cutting edge. Both feature the same nested titanium liners, framelock construction, and swappable scales in materials like G10, Micarta, and carbon fiber. If you want maximum pocket-friendliness, go Neutron. If you want a fuller grip, go Atom. Either way, you're getting exceptional quality.
What's the deal with TRM scales?
One of TRM's signature features is customizable scales. Don't like the color? Swap them. Want contoured instead of flat? Buy a new set. The TRM community actively trades and sells scales, creating an entire ecosystem around personalizing your knife. From jade G10 to carbon fiber overlays, there's always something new dropping.
Started in a kitchen?
Yes. In 1997, Les and Marianne Halpern launched what would become Halpern Titanium from their Massachusetts kitchen, using $2,000 worth of titanium scraps. They built a reputation supplying precision parts to major knife brands before launching TRM in 2014. That decades-long experience shows in every knife—these aren't designed by marketers, they're designed by people who've been machining titanium since the '90s.
What about warranty and service?
Limited lifetime warranty against defects in materials and craftsmanship. You're dealing directly with the people who made your knife, not a call center overseas. TRM stands behind their work.
