Overview & First Impressions
The Firefly JM16 is the compact charm of the Trivisa launch, a sub-three-inch folder that comes in three very different personalities: black micarta, green micarta, or a solid copper handle on the Firefly-CU. Under every skin sits the same 14C28N blade and the same slick crossbar lock. The result is one of those rare folders that works as a serious small carry and as a collector's set, since the three versions cost little more than one premium folder from the big houses.
Materials & Construction
Sandvik 14C28N is the smart money steel for small blades: fine-grained, takes a razor edge, and shrugs off moisture better than the carbon steels in this price bracket. The micarta versions wear textured canvas scales over steel liners with a warm, broken-in feel from day one. The copper variant carries real heft for its size, roughly an ounce more, and develops a deep amber patina that every collector photographs. All three share washers, Torx hardware and a deep-carry clip.
Design & Details
The blade is a leaf-shaped drop point with a full flat grind and a pronounced choil, tuned for detail work: zip ties, strings, apple cores, envelope corners. The handle fills a medium hand without hot spots and vanishes in a front pocket at just over two ounces. Jimping sits on the spine above the lock channel, and the crossbar travel is short and positive. Of the three, the copper Firefly-CU is the looker, while the black micarta is the quiet daily driver.
Real-World Use
Small knives live or die on ergonomics, and the Firefly passes the two-finger test: even with a two-finger grip on the choil, the cuts stay controlled and the lock stays put. For daily errands, food prep at the desk and the thousand small cuts between sunrise and sunset, it is exactly enough knife. 14C28N keeps its working edge for a week or two of city duty, and a quick touchup brings the hair-popping bite straight back.
Ownership Notes
The copper model needs a decision rather than maintenance: let it patina into character or polish it back monthly with a commercial copper cleaner. Both are valid, and the patina route protects the metal underneath. The micarta models are near-zero upkeep; a toothbrush and soapy water handle a year of grime. All versions take a light oil drop at the pivot seasonally and keep their silky crossbar action indefinitely. Stacked against other small EDC knives, the Firefly wins on steel consistency: every trim gets the same 14C28N, so the only real choice is personality.
Who Is This For?
This is the knife for people who found their perfect size years ago and stopped looking: sub-three-inch, light, friendly in the hand and inoffensive in an office. The copper version doubles as a gift that looks triple its price, and the micarta pair makes an honest work and dress rotation. Collectors of folding knives will want the full trio on the shelf, and honestly, at these prices that is not an unreasonable plan.
Final Verdict
Pick the black micarta Firefly if you want one small knife to forget about until needed, the green if you like a bit of personality, and the copper if you want the one people remember. The platform underneath is identical and genuinely good: solid lock, decent steel, thoughtful geometry. EdcMall has all three variants from the debut drop, and the copper one will likely sell out first, so move accordingly.
