Kunai by NAJA EDC

What the NAJA EDC Kunai Is The NAJA EDC Kunai is a multi-function, mechanical, everyday-carry fidget tool designed more for tactile play and engagement than for cutting or utility use. Its shape is inspired by the traditional Japanese kunai tool — familiar from ninja lore and anime — but in this case, that inspiration is aesthetic rather than functional as a weapon. It’s the first product from NAJA EDC and is aimed at people who like interesting mechanical EDC gadgets you can hold, manipulate, and play with.  Main Features & How It Works  Slider Section The front part of the Kunai includes a mechanical slider that you can push back and forth with your thumb  The factory setup gives a segmented feel (little clicks as it moves), but tracks are designed to be interchangeable for different feels.  Rotating Wheel At the back is a ring-like wheel that spins. It interacts with a magnetic feedback system — depending on where the bolt is positioned, the wheel either spins freely or gives a tactile, magnetic click feedback.  Bolt-Action Mechanism In the center is a movable bolt that doubles as a mechanism to change the wheel’s mode (magnetic vs free spin). Moving that bolt changes how the tool feels and responds.  DIY / Customization Most parts (except the tracks screwed in place) can be disassembled by hand, letting you customize springs, beads, or components if you like tinkering. Materials & Specs Material / Finish Price (USD) Weight Feel & Characteristics          Stainless Steel + PEI $229.00 75 g Heavier and more solid in hand, the PEI parts (plastic-like) add contrast in feel and texture. Good choice if you enjoy a more tactile, “chunky” slider experience.            Titanium (Silver) $319.00 90 g Slightly lighter overall than steel in other tools, but heavier than SS/PEI here because of design balance; titanium feels warmer/cooler in hand and is more premium. Great for collectors.         Titanium DLC (Black) $339.00 90 g Same physical characteristics as the silver titanium but with a DLC coating that adds scratch resistance and a sleek, stealthy look. Premium finish + tactile feel.     What This Means in Practice Weight Feel: The stainless + PEI version at 75 g feels substantial yet quick to flip, ideal for frequent fidget play. The titanium versions at 90 g have more momentum when you spin, slide, or manipulate them — many users find this premium feel more satisfying and “solid.”   Temperature & Texture: Stainless steel + PEI has a mix of metallic coolness and warmer plastic feel (PEI). Titanium stays neutral to the touch, aging with a softer patina over time and feeling smoother against skin.  Durability & Collectibility: Titanium is generally more corrosion-resistant and regarded as a premium metal among EDC enthusiasts. The DLC black finish adds extra scratch resistance and style, making it the most collectible option. The design deliberately doesn’t function as a blade or tool for cutting — its value lies in the interaction, feel, and mechanical play, much like EDC fidget gadgets people carry to keep their hands busy.           Who It’s For This kind of EDC item is great if you like: Tactile mechanical interaction — something engaging to fidget with. Collectible EDC pieces with cool designs and materials. Conversation-starting gear that’s different from typical knives or tools. It’s not primarily a utility tool (like a knife or multi-tool), but more of a pocket gadget with satisfying mechanical motion, similar in spirit to high-end fidget sliders and tactile toys.     Here's how it works:
