Product Name: EDC Outdoor Multifunctional Key Tool Octopus Bicycle Repair Tool 12-Function Screwdriver Color: Cool Black, Silver Gray. Please leave a note when placing your order, otherwise the color will be shipped randomly Weight: 27 grams Process: Mechanical Machining Material: Stainless steel Functionality; a tool that packs more practical functions into a minimal size, which can be considered an EDC eco-friendly tool. It is easy to operate and carry, made of durable metal, and features a variety of practical screw heads [from 3MM-10MM external hexagon screw heads, 1/4 universal socket, bottle opener, bicycle rim tension adjuster, flathead, Phillips head, T10 torx head, independent screwdriver, etc.]. Here, I will mainly talk about one of them, the T10 torx head [to solve the problem of how to secure annoying T10 screws, such as M48, SOG axe, and BANCHMADA141, you just need to use the T10 torx head, unless you keep the axe screws loose and can do without the T10 fastener]. In terms of functionality, there is a bottle opener feature, but the operation may be a bit awkward and requires some practice. After all, it is just a tool operated between two thumbs, and the leverage force is limited. And when you put it on your little finger, the "octopus" instantly transforms into a self-defense weapon. Configuration: In addition to the "Octopus" body, it also comes with an independent screwdriver bit and a 25mm diameter 304 stainless steel key ring Tip: 1. This product is finely processed to ensure it is free of any imperfections 2. The black version of this product uses the QPQ process, which provides a matte texture and a durable coating. It is not like other manufacturers' simple spray-painting process, which is prone to chipping and leaves water-like streaks on the surface Usage illustration:
