Talk:Magnetic Tool Holder
These can be pretty good, along with a good tool belt and/or Tool Tether System and/or a good Ladder with a good "tray" (for lack of a better word)
Some ladders just have one or two small holes, some of the Fiberglass Ladders at work have the near perfect setup. A larger oval shaped hole for your Lineman's Pliers , a thin slot for your Wire Strippers , a few screwdriver sized holes, a dish/tray, and a few also had a magnetic spot (Great for keeping Metal Electrical Box ("4 Square Boxes" ) 's lids from falling off your ladder and best case scenario making a loud cymbal sound, worse case scenario clocking someone on the head and if they don't have a Hard Hat on probably doing some damage )
Finally i have this Flashlight which also has a Laser Pointer (A Near-Must for a Jobsite in my Biased Opinion) and a magnetic base. When in your pocket via the clip it holds a few screws perfectly :)
That's my take on this after seeing it in passing when looking for the page on Magnetic Primer aka Ferromagnetic Paint
