Definitions

  • This invention relates to a pocket tool having an implement, such as a knife or saw. More particularly, the present invention relates to a foldable knife having a finger opening for providing a user with better control of the knife during a cutting operation.
  • Pocket tools such as foldable knives and saws are well known in the art.
  • these tools include a housing, which also serves as a handle, and a knife or saw blade coupled thereto.
  • the blade which is movable between a stored position and an extended position, is pivotally coupled to the housing at an end thereof. When not in use, the blade may be compactly stored in the housing. When the blade is in the extended position, the tool may be used to perform a cutting operation.
  • a folding knife in accordance with another aspect of the invention, includes a handle, a blade and a locking mechanism.
  • the handle includes first and second ends and a pair of side walls extending therebetween.
  • the handle has a longitudinal slot disposed between the side walls.
  • the handle has an opening formed in the pair of side walls proximate the first end.
  • the blade which includes a cutting edge and a shank portion, is pivotally coupled to the handle at the first end.
  • the blade is rotatable between a folded position, in which the blade is housed in the longitudinal slot of the handle, and an extended position.
  • the shank portion of the blade has an opening formed therein, which coincides with the opening in the side walls of the handle.
  • the openings are adapted to receive a user's finger and to improve the user's control of the knife during a cutting operation.
  • the locking mechanism which is coupled to the handle, engages the blade to secure the blade in either the folded or extended position.
  • an improved folding knife in accordance with still another aspect of the invention, includes a handle and a blade pivotally coupled thereto.
  • the blade includes a cutting edge and a shank portion.
  • the improvement includes at least one opening formed in the shank portion of the blade. The at least one opening is adapted to receive a user's finger and to improve the user's control over the knife during a cutting operation.
  • FIGURE 2 is an exploded, perspective view of the folding knife of FIG. 1 with the blade shown in the extended position; and FIGURE 3 is a cross-sectional view taken generally along the line 3-3 of FIG. 1.
  • the handle 12 includes a first end 16 and a second end 18.
  • the handle 12 also includes a pair of side walls 20, which extend between the first and second ends 16 and 18.
  • the handle 12 is preferably made of a durable plastic material and may be injection molded or otherwise formed. Disposed between the side walls 20 of the handle 12 is a longitudinal slot 22.
  • the longitudinal slot 22 receives the blade
  • the handle 12 has a top edge 24 and a bottom edge 26, both of which extend from the first end 16 to the second end 18.
  • the top edge 24 is arcuate in configuration and tapers toward the second end 18 where it converges with the bottom edge 26.
  • the bottom edge 26 has a curved portion 28 adjacent the first end 16 and a generally straight portion 30 proximate the second end
  • the curved portion 28 of the bottom edge 26 includes a recess 32.
  • the recess 32 provides access to the blade 12 when it is in the stored position.
  • the recess 32 provides an ergonomic support against which a user's finger may rest while gripping the knife 10.
  • the folding knife 10 may further include a belt clip 66, mounted to the handle 12 about the bearing member 36, for coupling the knife 10 to a belt (not shown).
  • the folding knife 10 further includes a locking mechanism 52 (see FIG. 1), which is mounted to the handle 12.
  • the locking mechanism 52 engages notches 54 (FIG. 2) formed in the shank portion 46 of the blade 14 to secure the blade 14 in either the folded or extended position. As shown in FIG. 2, the notches 54 are located along an edge of the shank portion 46 and are diametrically spaced about the opening
  • the folding knife 10 operates as follows.
  • the blade 14 When not in use, the blade 14 is housed in the longitudinal slot 22 of the handle 12, with the locking mechanism 52 maintaining the blade 14 in the stored position.
  • the lock pin 56 is depressed, disengaging the dowel 64 from the notch 54.
  • the user may then extend the blade 14 by grasping the portion of the blade 14 exposed by the recess 32 and rotating the blade 14 with respect to the handle 14.
  • the locking mechanism automatically engages the blade 14, as the spring 62 urges the dowel 64 into the notch 54. The blade 14 is thereby locked in the extended position.
  • the user would grip the handle 14 with the index finger extending through the opening 40 of the bearing member 36 and the middle finger resting against the recess 32.
  • the configuration of the folding knife 10 is such that it enables the user to maintain better control of the knife by providing a stable and secure handle 14.
  • the blade 14 may be stored by depressing the locking mechanism 52 and rotating the blade 14 back into the longitudinal slot 22 of the handle 12.
