Reinforced corner design for tool bags: high abrasion zones
A lot of tool bags look strong when they are brand new. The fabric feels thick, the handles feel solid, and the bag gives the impression that it can survive years of rough use. But on real job sites, the first serious damage usually does not start at the zipper or handle. It starts at the corners. That is where the bag scrapes the ground, hits truck beds, rubs against concrete, and carries the pressure of heavy tools day after day. Once the corner starts wearing through, the whole bag begins to lose shape, strength, and reliability.
