During the last year I bought a few electrical tools. The squeezer is important and this one has interchangable dies for different kinds of electrical terminals. This one is a Proskit crimper.
The gun looking thing is a tie wrap puller. This one is Boeing surplus bought thru ebay. It works great at pulling and cutting tie wraps so that no little sharp point is left behind.
Then I did finally buy a Fluke Multi-meter. I could probably get by with the $25 dollar Radio Shack meter, but there's nothing like having a Fluke. It will be an heirlum. I'll pass it down to generations to come.
