This is a holder for pliers used in lure fishing, etc. It is designed to be as compact as possible, without getting in the way of fishing. It can be used with pliers of a simple shape like the ones in the photo, from small sizes to industrial long-nose pliers. (The pliers in the photo are for reference only and are not included.) The pliers are secured with a spring hook, and the lock can be easily released by simply pulling them out when using the pliers. The belt attachment side uses a jumper hook, so it is firmly secured and difficult to detach. Please refer to the dimensions in the photo for the size of the belt attachment side (this product is a vertical attachment type, so please be careful). This is a handmade product sewn by hand with genuine cowhide leather. If it gets wet, please dry it in the shade, and occasionally maintain it with oils to keep it in good condition for a long time.
