"Pedro's cone wrenches are made from 2mm thick, precision laser cut, heat-treated tool steel and are revered for outlasting many other ""shop quality"" cones wrenches. Pedro's designed each cone wrench to fit perfectly, protecting the hub and ensuring simple and safe usage for the mechanic. Each flat wrench also features a single-ended design with ergonomic cushioned grip to provide maximum leverage & comfort. The updated shape features a smaller head profile for better clearance and a longer handle for improved leverage and control. Backed by Pedro's lifetime warranty."
