Abstract: The v-cut knife of the present invention has a handle connected to a blade section comprising a blade with a proximal end, a distal end, a top surface and a bottom surface. The bottom surface is formed into a sharp cutting edge. A generally v-shaped section is disposed between the proximal and distal ends of the blade. The v-shaped section is shaped and configured to cut away a waste portion of a plant from the useful produce portion. The knife is particularly useful for cutting the tail portion of a Romaine lettuce plant so as to maximize the amount of produce portion remaining after removing the waste core portion of the plant. When configured as described herein, the knife efficiently and safely cuts the tail section of a Romaine plant so as to leave as much produce behind as possible.
