Using the Klein 5165 tool pouch is easy. First, decide which tools you need for the day and place them in the appropriate pockets. The large utility pockets are great for bulkier items, while the pliers pockets keep your pliers secure, and the screwdriver loops hold your screwdrivers neatly. The knife snap is perfect for attaching your knife. When it comes to wearing the pouch, simply slide your belt through the slotted design. Make sure the belt width is within the 2 - inch (51 mm) limit. As for maintenance, try to keep the pouch dry as much as possible. If it gets wet, let it dry naturally in a well - ventilated area. Occasionally, you can apply a leather conditioner to keep the leather soft and prevent cracking. Avoid exposing it to sharp objects that could damage the leather. With proper use and care, this tool pouch will serve you well for a long time.
