1. A cutting tool comprising:
- a first handle having a recessed receiving region adapted for retaining a workpiece, a distal end, and a body extending between the receiving region and the distal end; and
a second handle pivotally and releasably coupled to the first handle, the second handle having a blade attachment portion, a distal end, and an intermediate region extending between the blade attachment portion and the distal end, the second handle defining a hollow blade receiving region accessible through a blade receiving slot, the hollow blade receiving region defining a relatively flat blade receiving face, the second handle further having at least one blade retention member projecting from the blade receiving face and permanently affixed to or integral with the second handle, within the hollow blade receiving region.
