You’ve seen magnetic levels before, but how about a level where you can turn the magnet on and off like a Magswitch™? Strong Hand Tools incorporates a switchable magnet in their Mag-Level with 50 lbs. of holding force. You get a level with a magnet strong enough to securely hold the tool, yet you don’t have to brace yourself with your foot to pry it off the surface.
Strong Hand Tools built three bubble vials into the Mag-Level: one each for level, plumb, and 45°. The magnet turns on and off with the flick of a switch. The 2 lb. level measures 16″ long by 1″ deep and is 4″ wide at the widest point.
Pricing for the Mag-Level starts at $30. I did see these at Harbor Freight a few weeks ago for $20, although their website doesn’t confirm the price.
