Handy!

This 32 blade feeler gauge set is perfect for my automotive tools set. When you are working on a car and putting the engine back together you have to be very precise on your measurements. A miss gapped piston or spark plug can wreak havoc on the firing of the engine and burn it up or blow it apart. These are well enough made since they have to be pretty thin in places to be the right gap. There are both metric and inch measurements making this perfect for any of my vehicles. (I only have 7 at the moment!) I love being able to know I am getting the right measurement. They all close up into on long compact tool so easy to carry in my pocket or find a place for in my toolbox. Great!
