Here's a way to get more life out of an old hacksaw blade. Mount it on the side edge of your workbench with about half the width of the teeth sticking up over the top surface. This will give you a handy cutting tool. Make sure that the location of this cutter is both easily accessible as well as away from frequent brush up traffic.
When you reorganize your basement or garage, buy yourself a number of cardboard boxes all the same size instead of scrounging various-sized used boxes. This way they will all have covers and you can stack them neatly. Mark each box with a big letter and number, like A-1, A-2, etc., on all four sides and top. Use a three-ring binder to write down the box number and its contents.
