Hiroaki Ohta, a skilled artisan based in Tokyo, Japan, is renowned for his masterful craftsmanship in the realm of fixed blade and folding knives. With a focus on precision heat treatment techniques and exceptional leather sheath-making skills, his creations truly stand out. The utilization of carbon fiber, recognized for its remarkable strength and lightweight properties, makes it an excellent choice for the handle of Ohta's pocket knives. The minimal weight of carbon fiber beautifully complements the compact dimensions of the blade, resulting in an ideal pocket knife design for those who want to travel light. Crafted from D2 steel, a high carbon, high chromium semi-stainless steel akin to SKD-11, these fixed blade knives excel as versatile tools. Notably, this steel exhibits remarkable wear-resistance; however, it will take a bit longer to sharpen. The blade will patina at a much slower rate than carbon steel. It’s important to make sure it is completely dry before storage to prevent rust. Should the stainless folding pin become loose over time, a gentle tap with a hammer on the joint will effectively tighten it.
