Claim:
1. A tool for creating impressions of downhole objects comprising: (a) a cylindrical outer casing; (b) a top plate that is situated inside of the outer casing at a top end of the tool; (c) a plunger that is situated directly underneath the top plate; (d) an end plate that is situated inside of the outer casing at a bottom end of the tool; (e) a lever with a top end and a bottom end, the lever being situated within a longitudinal slot in the outer casing; (f) a pressure lock plate; (g) a pressure base that is situated beneath the pressure lock plate; (h) a main spring platform that is situated beneath the plunger, the pressure lock plate being situated beneath and spaced apart from the main spring platform; (i) a main spring that is situated between the plunger and the main spring platform; and (j) a plurality of elongated rods that are not attached to the main spring platform but extend from beneath the main spring platform through a plurality of holes in the pressure lock plate, through a plurality of holes in the pressure base, and through a plurality of holes in the end plate, wherein each of the plurality of elongated rods is surrounded by a rod spring and a collar that is situated below the rod spring, and wherein the rod spring on each of the plurality of elongated rods extends from a bottom of the pressure base to the collar; wherein the pressure lock plate moves laterally when the lever pivots from a locked position to an unlocked position, thereby aligning the plurality of holes in the pressure lock plate with the plurality of holes in the pressure base and enabling the elongated rods to move longitudinally within the tool and make contact with the downhole object to form the impression.
