A cutting tool has respective first and second tool members cooperating to effect a cutting stroke between an open position and a closed position. The cutting tool has a first tool member having a first handle rigidly connected to a first cutting member, and a second tool member including a second cutting member pivotally secured to the first cutting member and including a tab and an elongated shank portion formed thereon and defining a channel therebetween. The second tool member further includes a fulcrum rigidly secured to the second cutting member and configured for sliding interaction with the shank portion of the second cutting member to effect the cutting stroke. In addition, a locking member is slideably mounted in a longitudinally extending slot formed in the first handle. The locking member is slideable within the slot from a locked position in which it is received within the channel to an unlocked position in which it is located outside of the channel.
