A seafood sheller for cracking or cutting open shells of, for example, crustaceans is described herein. The seafood sheller having a handle member, an upper beak member and a lower bladed member. The upper beak member extending longitudinally forward from the handle member and having a distal end opposite from the handle member and an upper beak member bottom that extends longitudinally from the handle member. The lower blade member having a blade edge and a blade base, the blade edge extending longitudinally forward beneath the upper beak member bottom from the blade base. The blade base being connected to the upper beak member at a rearward portion of the upper beak member bottom. The lower blade member further having a distal end opposite from the blade base, the distal end of the upper beak member longitudinally extending forwardly beyond the distal end of the lower blade member.

A landscaping dripper system tool that safely enables releasing drip irrigation feeder pipe from the barbs of connected fittings and end-point devices; emitters, sprayers, manifolds, etc. The tool includes a channel and a parallel, recessed knife blade that receives and cuts the irrigation tubing wall, releasing the feeder pipe from the connected barbed fitting. The knife blade tip extends into the channel to a depth based on a standard irrigation tubing wall thickness, so when the operator slides the tubing with attached barb along the channel, the tubing wall is safely cut.

A hand-held cutting tool includes a handle and a cutting head with an embedded tool having multiple operative surface portions, the embedded tool consisting of a single unitary metal piece, the multiple operative surface portions thereof including a cutting edge and a tape splitter portion, the embedded tool being molded or otherwise secured within the cutting head such that the tape splitter portion distally extends from the cutting head and a portion of the cutting edge is exposed. The embedded tool includes a top flat surface section which is part of and defined by an uppermost structural reinforcing portion of the single unitary metal piece; and the tape splitter portion is recessed in relation to the uppermost structural reinforcing portion relative to the cutting edge of the blade.

A knife includes a body including a first end, a second end opposite the first end, and a longitudinal axis that extends centrally through the first end and the second end. The knife further includes a first scoring tip that points in a first direction, a second scoring tip that points in a second direction opposite the first direction, and a scoring tip axis that extends centrally through the first scoring tip and the second scoring tip. The scoring tip axis is perpendicular to the longitudinal axis. A chisel extends from the second end of the body and the longitudinal axis of the body extends centrally through the chisel.

Contemplated cutting systems are provided that include a blade, a blade holder, and a non-cutting surface. The non-cutting surface is configured to contact a surface to be cut. As the cutting system is moved across the surface and the non-cutting surface is rotated against the surface, the blade is configured to (i) pierce the surface with a first piercing edge and (ii) cut the surface with a first cutting edge. Contemplated cutting systems can be incorporated into hand or machine operated cutting tools.

An ergonomically designed, auto-retracting utility knife that can safely remain in the user's hand while performing non cutting tasks. This invention allows a person to continue with the jobs they were performing by having the ability to use both hands and not having to set the utility knife down between manual tasks, thus saving time and increasing efficiency. An auto-retracting blade decreases the risk lacerations and other hand/wrist injuries to the user and others during routine use of the knife.

A safety utility knife includes a resin-made grip part, a blade projecting from the grip part, and a resin-made head part arranged at a tip of the projecting blade. The blade is formed with a through-hole so that a resin-made coupling part lying within the through-hole couples together the grip part and the head part that are made of resin. Since the safety utility knife of the present invention allows the three resin-made parts to be joined together, it can be manufactured easily and at low cost using a 1-gate type mold. Also, there is no unnecessary increase in the blade thickness, preventing an increased cutting resistance and a rough cut end from occurring.
