A lot of EDC brands are obsessed with getting bigger. Jimmytronics has spent four years doing the exact opposite. The New York studio built its name on tiny, genuinely weird everyday-carry pieces — most famously the titanium Sardine Nano, a micro tool that ships sealed inside an actual peel-open sardine can. Now, for the first time, the team is thinking full-size, and the result is the Tarpon Utility Knife.
The naming is deliberate. A sardine is bait; a tarpon is a six-foot silver missile that fights like hell when you hook it. The jump in product scale tracks perfectly. Where the Sardine ran miniature X-Acto craft blades, the Tarpon accepts any standard utility blade — the same cheap, replaceable rectangles you can grab at any hardware store — which instantly makes it a far more practical everyday carry.

Built like a tool, sized like a money clip
The body is machined from solid 316 stainless steel and held together with 416 stainless Torx hardware — no plastic, no flex, no creaks. Fully assembled it measures 4.69 inches long and weighs 100 grams, but the number that actually matters is the thickness: just 8.5 millimeters, roughly a short stack of quarters. That makes it slimmer than almost any folder you'd otherwise be pocketing, which is precisely the point.

A few practical touches round out the package:
A Cerakoted 17-7PH stainless wire clip, offered in a handful of colorways, handles pocket duty
A lanyard hole for those who prefer a pull-tab draw
A knurled disc up front that swaps blades with nothing more than a simple twist — no screwdriver required
A switchblade that isn't
Here's the fun part. The blade fires out the front of the handle rather than folding out the side, so at a glance the Tarpon reads like a $400 out-the-front automatic. But unlike a true OTF, there's no stored energy waiting to launch it. You're the one doing the launching.
The sequence is simple: a press of the Fin Lock releases the blade, a push of the slider — or a lazy wrist snap, if you're feeling showy — sends it forward, and it clicks home locked. A TC4 titanium spring adds a bit of mechanical reassurance to the whole thing.

The result is a fully manual, fully ambidextrous action that scratches the same fidget itch as a premium automatic, but with a fraction of the mechanical complexity — and none of the legal headaches, since a manual slider is a different beast entirely in most jurisdictions.
The Tarpon is live on Kickstarter now with pledges starting at $68. Each knife ships with a spare blade in the box, and like everything Jimmytronics makes, it's backed by a lifetime warranty. For anyone who's outgrown the pocket-knife-adjacent micro tools and wants something genuinely useful, the Tarpon is a strong argument that bigger can still be clever.
