I've been graced with several pairs over the years... and usually they are not sharp enough. However, I did have one that was a dream..... I could cut up to 3 layers of heavy denim ( with out a groan) with it when I was testing them out... clean as a whistle..... I cut tons of stuff out with them ( they were vintage-- when I got them), used them for years.... then one day half way thru a cut , they died.... guess the motor just wore out.... I've not found a good set since.....they are mint green but can't recall the brand
* mine were a corded electric set.. not battery operated*
