Tanto blades were originally developed for armor penetration, ground with a reinforced tip geometry that could punch through hardened surfaces where a conventional drop point would snap or deflect. That heritage tends to disappear when the profile gets shrunk to keychain scale, mostly because the execution rarely holds up at that size. The geometry promises precision and the material delivers something fragile. TiMav’s Natanto takes the tanto format at its word, pairing the profile with a D2 tool steel blade that carries a 2.7mm spine, the same thickness found on full-size production folders, and a 15-degree V-grind on each side that keeps cutting resistance genuinely low.
The whole knife closes to 39.7mm and weighs 10.8g, which makes the spec list that follows feel like it was lifted from a larger product. The Grade 5 titanium frame is CNC-milled from a solid billet, no welds, no seams, no structural compromise. Dual brass washers carry the pivot with smooth, even resistance rather than the spring-loaded snap of ball bearings. A frame lock clicks into place at full extension and stays there until deliberately released. The 4.5mm keychain aperture threads onto standard rings, bag pulls, and headphone cases without forcing, and two finish options, sandblasted titanium and PVD black, round out a package that ships worldwide with no additional charge.

D2 tool steel is a fitting choice for a knife this small because edge retention matters more when the blade gives you very little room to waste motion. Natanto’s modified tanto shape concentrates that usefulness into the tip, giving it the kind of precise entry that helps with tape seams, plastic blister packs, zip ties, and other annoying materials that usually punish tiny blades first. The 15-degree V-grind on each side keeps the knife slicing cleanly instead of wedging its way through a cut, and the 2.7mm spine adds the kind of stiffness that makes the blade feel planted rather than flimsy. For a micro folder, that thickness changes the experience immediately. You press down and the blade holds its line.
Closed, the knife is only 39.7mm long, or 1.56 inches, and when opened it stretches to 63.3mm, about 2.49 inches. It weighs 10.8 grams, roughly 0.38 ounces, which puts it firmly in the category of tools you can forget you are carrying until the exact moment you need them. That is really the whole appeal of the Natanto. It is sized for the kind of cutting jobs that appear constantly and disappear just as fast, opening deliveries, trimming loose threads, cutting tags, slicing tape, nicking into sealed bags, or cutting zip ties without fumbling for scissors. TiMav clearly designed it for people who want a real blade on hand without committing to a full-size folder in their pocket.
That sense of seriousness carries into the frame too. The handle is made from Grade 5 titanium and CNC-milled from solid stock rather than assembled from multiple cheap parts. At the same strength, titanium comes in far lighter than steel, which is exactly why it makes sense on a keychain knife where every gram counts. The frame has milled finger channels that create actual indexing points for your grip, a small detail that matters more here than it would on a larger knife. With a tiny form factor, control is everything. A slippery handle turns every cut into guesswork, while a shaped frame lets your fingers settle into place quickly and keeps the knife from shifting mid-cut. The handle measures 13.7mm wide and 7mm thick, enough to feel stable in hand without becoming a bulky object hanging off your keys.
Opening the blade looks refreshingly free of gimmicks. Natanto uses dual thumb studs placed for a natural pinch motion, so you are not digging at a nail nick or trying to pry the blade loose with a fingertip. The action rides on dual brass washers, which gives the movement a measured, deliberate feel rather than a loose, snappy flick. That suits a knife this size much better. Once open, the frame lock engages with a distinct click and holds the blade securely in place. TiMav also claims the blade floats within the titanium frame when closed, avoiding internal contact and wear over time, which should help preserve the action instead of letting it get sloppy with repeated use.
The Natanto closes to 39.7mm, making it shorter than a standard house key, and weighs 10.8 grams, lighter than half an AA battery. That size makes it smaller than the average house-key, earning a place on your keychain. The 4.5mm keychain aperture accommodates most keyrings, carabiner clips, and bag pulls without forcing or scraping. This is a knife for people who want a blade available without the commitment of pocket carry. It sits on your keys, in your EDC pouch, or clipped to a belt loop, and it handles the micro-tasks that tend to accumulate throughout a day. Opening mail. Cutting tags off new purchases. Stripping wire insulation. Breaking down a shipping box. Tasks that take seconds with the right tool and minutes without one. Just remember to take it off your keys when traveling by flights, since the knife isn’t airline-compliant.
Two finish options are available: sandblasted titanium, which carries a raw, matte surface, and PVD black, which adds a stealth coating over the titanium frame. Both finishes share the same construction, materials, and engineering. The Natanto is currently available for $32 USD, with free worldwide shipping included.
