For a simple molded piece of plastic with a blade, this is an incredibly useful tool for stripping the outer insulation only and punching down the connections into network jacks. I lost the last one I had and had to buy one again when I recently expanded my home network, and it's well worth the dollar to have.
We are small group of performing musicians on a tight budget. MCM products have worked very well for us. Always looking for more live sound deals.
