Its pipe slide system protects the lead from breakage, ensuring clean, smudge-free writing. With a sleek black body and double-speed rotation engine, it’s engineered for precision, durability, and a premium writing experience favored by professionals and students alike. ## Description The Kurutoga has a core rotation mechanism that continually rotates the pencil lead as you write. A spring-loaded clutch twists the lead incrementally every time you lift the pencil from the paper. This allows a uniform wearing of the lead so that it always remains pointed. This is great for students! It gives you an amazingly thin line. In effect, you use only 50% of the lead area that you were previously using with your old mechanical pencil. In addition, this new Kurutoga is equipped with a pipe slide system.The lead is difficult to break as you write, due to the innovative mechanism. When the core is reduced, the pipe gets shorter at the same time. The guide pipe protects the entire length of the lead. Because there's no lead breakage, your papers remain clean without smudges from broken lead dust. Review: The BEST mechanical pencil! - The uni kuru toga pipe slide is way better than those low quality plastic ones - this one is great quality, feels great to hold. The design is beautiful, I love how the mechanism looks, the turning mechanism is really nice to write and sketch with. The pipe slide model has the W Speed engine, which means the turning mechanism is 2x the speed of the standard model, and there is a massive difference! Another pro is the 0.5mm lead - way better than 0.7 or 0.9 in my opinion, the sharp 0.5mm paired with the turning mechanism gives amazing handwring results. And it has worked with many different brands of lead.
