Brian Fellhoelter came to pens from custom knifemaking, and the TiBolt he machined as the original titanium bolt-action pen set the pattern half the EDC pen world now follows. Every pen is CNC machined and finished in the USA to knife-grade tolerances: Grade 9 titanium bodies over Grade 5 internals, titanium torx screws for field disassembly, and a spring-loaded bolt that deploys the tip with the same satisfying action as the mechanism it's named for.
The full-size TiBolt runs about 5.5" of 100-percent titanium construction, body, bolt, clip, and cap, with only the spring, O-ring, and refill excepted, and it accepts Parker-style, Fisher Space Pen, and Schmidt EasyFlow refills so the ink is never the limitation. Finishes range from sterile and stonewashed bodies through spiral and straight flutes to laser engravings including Dragon, Warthog, Stars, and WWII patterns, with Deluxe versions adding milled grip texture and two-tone treatments mixing finishes on one pen.
The TiCkler brings an alternative grip profile, the compact TinyBolt takes Lamy M22 refills, and G2 versions shorten the full-size format for pocket carry, joined by the Mark 22, machined pencils, and the one-off Captain Axel laserwork customs. Beyond titanium, copper adds writing heft and a living patina, brass brings traditional warmth, and zirconium models offer the darkest, hardest-wearing option in the lineup. They anchor the premium end of our machined pens collection.
