collaborated with a daily-use hardware brand to customize hardware blades and main components for household bottle openers. Using high-carbon steel material, through precision forging and sharpening processes, the blade is sharp and durable, which can easily open various bottle caps, save effort in operation, and is not easy to blunt or break. The anti-slip pattern design on the surface is firm to hold and not easy to slip. The connection is precision welded, firm and not loose. The surface is rust-proof, easy to clean, suitable for plastic and wooden handles. Portable and desktop models can be customized according to needs. This customized component helped the partner increase bottle opener sales by 41% and became an essential small hardware for home use.
