Revolutionary new design on blades and our cutter. Special heat treatment for each of our blade we make, gives our blade the perfect hardness for longer usage. Our special girding on our blades makes more shaper (no burrs) and durable. Equally alignment on each of blade makes the straight cut on the pipes. We polish each of our blades carefully to eliminate the liners on the blade surface, which makes the blade more smooth and durable. Strict quality control: we test our blades with latest hi-tech equipment to make sure the hardness of the blade meet our standard. Also, we apply fatigue test on our cutter with more than 500 times to make sure the cutters themselves, blades, and parts are still in perfect condition. We apply our special antislip paint on our cutter, that brings the users the extra friction while holding on hand, especially, it is perfect for people who are working in the wet and cold condition, they do not need to worry dropping or slipping off the cutter from their hand again. Our blades, ratchet, and spring are rust free finish, which brings the longer usage. We designed our cutter's handle based on ergonomic. The longer handle brings our users the extra comfort and also it's labor-saving. Our cutters are also perfect for female users. Die casting aluminum ally construction makes our cutter stronger which means you can apply for pressure.
