TRM Atom
Three Rivers Manufacturing released the Atom in 2019 and it quickly became the flagship of the TRM lineup, the knife most often responsible for converting curious buyers into lifelong fans of the brand. Knife owners describe the TRM Atom as a folding scalpel, and the numbers back the nickname: a 3.5 inch full flat ground blade cut from .090 inch stock, a total weight of just 3 ounces in flat G10, and slicing geometry that embarrasses knives twice its price. Every Atom is 100 percent manufactured and assembled in the USA, with USA etched on the blade and a limited lifetime warranty behind it.
TRM Atom Linerlock and Titanium Models
The standard Atom builds on pocketed titanium liners with custom titanium hardware and phosphor bronze washers, a linerlock platform that keeps the knife thin at .390 inches across the handle while leaving the scales fully swappable. The Titanium Atom takes the same profile upscale with precision machined titanium scales in 3D contoured Lizard Skin texture or Pinstripe finish, landing at 3.85 ounces and giving collectors a premium build without sacrificing the ultralight character that defines the model. Both versions carry a 6AL/4V titanium deep pocket clip configured for right hand tip up carry.
CPM MagnaCut and CPM 20CV Powdered Metal Steel
Atom blades come in CPM MagnaCut and CPM 20CV, TRM's signature pairing of modern powdered metallurgy. MagnaCut brings stainless corrosion resistance with toughness that belies its edge retention, while 20CV holds a working edge through long stretches of hard use. Every blade gets a deburring and two stage ceramic tumble and polish and arrives genuinely sharp from the shop. Our guide comparing every major knife steel puts both alloys in full context.
Over 30 Swappable TRM Atom Scales
The Atom supports more than 30 scale options across carbon fiber, Fat Carbon, CamoCarbon, G10, micarta, and titanium in flat, 3D smooth, and textured configurations, and the pocketed liner design makes swaps a few minutes of work with basic tools. Our knife handle materials guide covers how each material wears in the pocket and the hand. Browse the complete Three Rivers Manufacturing collection to see the Atom alongside the rest of the family.
