Kansept named this one after the planet that got demoted, and the joke writes itself: a 2.5-inch blade that is small enough to be overlooked. The Pluto K3129A4 runs rose gold S90V in blackwashed titanium with black micarta for $138.89.
The spec: 2.5-inch blade in CPM S90V with a rose gold coating, blackwashed titanium handle with a black micarta inlay, Munko Knives design. It is a genuinely small knife — the kind that fits next to a phone and a wallet without changing the shape of a pocket — and Kansept's copy leans into the compact-carries-everywhere angle.
Munko's handle geometry is worth a word as well: a short, neutral shape with a forward finger groove, which on a 2.5-inch blade means three fingers and a thumb rather than the two-finger pinch you get from most knives this size. S90V in a 2.5-inch blade is an odd but defensible choice. The steel's weakness is that it is hard to sharpen and not especially tough, both of which matter less on a knife that will never be used to pry and that needs an edge only 2.5 inches long. Its strength is wear resistance, which means a small knife that stays useful for a very long time between touch-ups. The rose gold coating adds corrosion protection on top.
Against Kansept's Lucero at $100 you pay $39 more for S90V instead of 154CM and a titanium frame instead of micarta over liners. Against the Nahual at $214.89 the Pluto is $76 cheaper, half an inch shorter and gives up MagnaCut and the crossbar lock. Against a CIVIVI Chronic at $57 you are paying for materials and finish, not for cutting performance.
Verdict: buy it as a second knife — the one that lives in a bag or a jacket and gets used when the primary is too big for the room. Skip it as a primary: 2.5 inches of S90V is a lot of money for not much blade, unless small is the point.
