A pair of adjustable pliers 10 is comprised of first and second plier halves 14, 16 pivotally and slideably joined together by a nut and bolt-type combination 18 fixed to the first plier half 14 and extending through a slot 23 in the second plier half 16. The second plier half 16 includes a series of arcuate grooves 24 cut into its interior surface, facing the first plier half 14. Correspondingly, the first plier half 14 includes an arcuate raised portion 28 that dimensionally matches and is pivotable within each of the arcuate slots 24. To adjust the jaw portions 21, 22 of the pliers 10, the arcuate raised portion 28 is selectively engaged with one of the series of arcuate grooves 24. In order to engage the arcuate raised portion 28 with a selected one of the arcuate grooves 24, the pliers 10 are manipulated to a fully open, adjusting position where the arcuate raised portion 28 disengages the arcuate grooves 24 and is positioned substantially parallel to the slot 23. In this position, the plier halves 14, 16 are slideable to the desired position. A ball-type latch 40 is secured to the first plier half 14 and extends in a direction generally toward the second plier half 16. A plate 30 is attached to the second plier half 16 and includes a linear groove 38 substantially parallel to the slot 23. When the plier halves 14, 16 are manipulated to the fully open, adjusting position, the ball-type latch 40 engages the linear groove 38 so as to urge the plier halves 14, 16 to remain in this fully open, adjusting position, thereby guiding the plier halves 14, 16 along a desired adjusting path.
