There is a whole category of carry that locking knives do not serve: places where a blade under two inches and no lock is the difference between legal and not. The CIVIVI Purr is built for that shelf, and it is a better knife than the category usually gets.
The spec: 4.61 inches overall, 1.83-inch Nitro-V reverse tanto at 0.1 inch stock, 59-61 HRC, stonewashed flat grind, 2.89 inches closed, G10 handle 0.41 inch thick, stainless liners, caged ceramic ball bearings, double detent slip joint, tip-up clip mountable left or right, 42 grams with the lanyard. Designer credit goes to Ostap Hel, and the orange, black and white G10 has a randomized color distribution, so no two handles look identical.
A double detent slip joint is the mechanism to understand. There is no lock bar, just two detents that hold the blade open and closed with a positive click, which means the knife is legal in jurisdictions that prohibit locking blades while still feeling like a modern tool rather than a friction folder. On a blade this short the flipper tab doubles as a guard, which is what keeps your fingers behind the edge.
A 1.83-inch reverse tanto is a task-specific shape: the straight edge fires on contact and the reinforced tip takes sideways pressure without snapping, which makes it a good package and tape knife. Nitro-V at 59-61 HRC holds a fine edge and shrugs off corrosion, and at 42 grams you will forget it is in a coin pocket until you need it.
Compared with a Victorinox Cadet, the Purr is heavier, more expensive and much better at opening boxes; compared with CIVIVI's own Baby Banter, it is smaller, legal in more places and missing the lock. Verdict: the knife to buy if a two-inch limit is your reality, and a good second knife if it is not. Skip it if you need to cut anything bigger than a mailer, because 1.83 inches is a real constraint.
