A level is a pretty simple tool so innovating it is a bit tricky, but that’s just what Empire has done with their UltraView LED Torpedo Level. Tiny LEDs surround the vial, lighting it up in the darkest spots. It is available at The Home Depot.
Some power tools haven’t made the leap to cordless because they simply require too much power. The belt sander used to be one of those tools, but RIDGID has changed that with this GEN5X unit. It is available at The Home Depot.
