Using this 33 - in - 1 pocket tool set is easy. First, decide which tool you need for the task at hand. For example, if you need to tighten a screw, choose the appropriate hex bit or socket and attach it to the ratchet handle. The magnetic socket will keep the bit in place. When using the safety hammer, make sure to hold it firmly and strike with controlled force. The safety belt knife should be used carefully in emergency situations only. The small knife is great for small, delicate jobs. For maintenance, after each use, wipe the tools with a dry cloth to keep them clean. Store the tool set in the compact zippered belt sheath to protect it from dust and damage. Avoid using the tools in extreme conditions like high humidity or corrosive environments to ensure they last a long time.
