A safety cutter adapted to open a box or similar packaging comprises a molded elongated handle which integrally connects with a protective head that mounts a fixed blade. The head extends transversely and has a protective canopy. Exposed portions of the blade, which is preferably ceramic, are protectively disposed at opposed portions of an upper end of the handle below said head. The handle has measurement scales and a contoured thumb grip.

An accessory tool for an oscillating power tool includes a mounting portion and a blade portion that extends from the mounting portion. The blade portion includes a first lateral edge portion, a second lateral edge portion, and a leading edge portion. A cutting edge is defined in the second lateral edge portion that includes a rearward facing portion that extends generally laterally from a distal end portion of the second lateral edge portion toward the first lateral edge portion and a forward facing cutting edge portion that extends from said second lateral edge portion toward said first lateral edge portion. The rearward facing cutting edge portion is at least partially interposed between the leading edge portion and the mounting portion, and the forward facing cutting edge portion is at least partially interposed between the rearward facing cutting edge portion and the mounting portion.

A hand-held cutting tool includes a handle, at least one cutting head with an embedded blade, the at least one cutting head being connected to the handle, and a clip connected to the handle within a recess thereof, the clip including a resilient member extending generally lengthwise along the handle. Each of the cutting head(s) is connected to the handle at an end thereof (i.e., at one or the other of two ends of the handle along a lengthwise portion thereof). The clip is connected at a base portion thereof to the handle at a location within (e.g., an interconnection location or juncture of) the recess. The clip is only connected to or in contact with the handle at the location independent of whether the resilient member (of the clip) flexes or otherwise repositions in relation to the base portion of the clip.

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.

The present utility knife provides a uniquely improved safety mechanism that increases safety, reliability, and reduces the cost of manufacturing. A shield is locked over the blade by a strut braced between the shield and a stop within the housing. The strut is biased to the locked position by an integrally molded sinuous spring that is designed to force the strut into engagement with the stop and to force the shield to cover the blade, allowing just one cut per actuator pull. The stop structure checks the motion of the strut when locked and closely guides the movement of the strut when unlocked through use of an L-shaped channel. These features reduce the complexity of the safety knife and increase the reliability of the safety mechanism under rough conditions.
