Having been growing my hair out the past couple of years or so so it is long. So see a hair laying on my sweatshirt and pick it up. Hold so it is hanging down and take my Shipley hunter/bush knife and flick at it twice and the first time doing so could feel the edge grab the single hair. Second little flick cut the hair in half with very little effort. Forged 5160 its whats sharp. keepem sharp
