What's your favorite tool in your toolbox, the one you can't leave home without?

The big, long-bladed yellow handled screwdriver, right?

You use it to do everything: to pry apart stubborn joints, as a punch or chisel, act as a temporary doorstop, maybe even now and then to screw or unscrew a screw. You've probably also used one, on occasion, to pierce a starter hole in a sheet metal duct, and to draw the edges together in order to install drive cleats.

Now, the FCT-M-D1, at 153/4 inches, from First Choice Tool Company, Sturgis, Mich., can become your official, every day duct stretcher and slicer. It works better than a big screwdriver. It has a notched blade to fit the lip of the duct, and an offset handle to protect the hands. FCT-M-X1, at 13 inches, is a handy companion tool that can be used to scribe a line or pierce and enlarge a hole in sheet metal duct.
