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.
The web site was easy to use, I found everything I was looking for. I like the one stop shop. I am telling all my friends about MCM Electronics.
