For anyone who needs to make precise marks, scribe circles, or transfer measurements on metal, wood, or leather, this flat leg divider is a pro-grade tool. It's made from high-hardness carbon steel, so it's tough and durable. The legs are 150mm (about 6 inches) long and have hardened, finely polished points that stay sharp for accurate marking. It features a hardened and tempered bow spring that keeps the legs under uniform tension – no wobbly side-play here. The adjusting screws have self-retaining washers and nuts, letting you quickly set the exact span you need. This isn't a flimsy school compass; it's a serious tool used in mechanical scribing, layout work, drafting, and more. Whether you're an engineer, machinist, woodworker, leather crafter, teacher, or student, this divider gives you the precision you need. It comes ready to use, no assembly required. If you're tired of cheap tools that can't hold a setting, this heavy-duty divider is a solid investment for your workshop.
