Query: Battery Operated...

I made the mistake of assuming the battery operated was a rechargeable battery. It runs on AA batteries which means you'll get better trims using a wooden block.It has virtually no "umph" to the blades which simply pulls instead of cuts.I went back and got a $10 more expensive blade that has a rechargeable battery pack and has a higher blade rate allowing for a true cut.
