When sharpening mower blades, I use conical rotary balancers that need a flat, level surface to work properly. For many, many years I have used a cheap plastic dosing scale in combination with a small torpedo level to ensure my surface is level in all directions. When I saw this 60mm Aluminum Precision Round Arrow Spirit Level, I decided to improve my leveling technique. After leveling up with my old levels, I checked my new toy again - - - I mean tools. All three levels were exactly the same. My new precision aluminum porthole level was just as accurate as the cheap levels I've used for years. The new level has finer gauges and also costs twice as much as the previous two combined. But peace is also worth something.
