Empire Level 36 Magnetic Polycast Protractor has been very useful to me as a maintenance technician. First let me say this is not an exact tool but I often need to know the angles of a stair rail or the slope of a lawnmower blade to get close to factory specs and this thing does the trick. A very handy and versatile tool for all kinds of angles/steps. It's plastic! It's not meant to be thrown around or stuffed in a tool bag, but given the price compared to what I've seen in "box stores", it works for me.
