I wanted a chopper to help me with preparing nightly salads and that would shred my lettuce and radishes/onions easily and quickly. Once I figured out the clockwise and counterclockwise requirements of locking and unlocking the chopper, I was set to go. The blade is very sharp and when it tapped my index finger when I took the blade out, I developed a blood blister, so please be very careful when handling the blade!
