An agricultural tool including a powered motor that supplies vibration to a tool implement. The vibration allows a user to dig with decreased effort, and also reduces the likelihood of severing a root on a plant by replacing the linear force required to dig with transverse vibration. The tool includes a one-handed grip, allowing the user a free hand to assist with gardening activities.

A tool comprising a handle and an implement. The handle comprises an elongate portion having a first end and a second end, and the implement, removably attachable to the handle, comprises an elongate portion at a first end and a tool portion at a second end. In an embodiment of the invention, the handle has, at the first end, a male portion comprising a reducing taper extending from the elongate portion and terminating in a shoulder, and a threaded portion extending from the shoulder and having a cross sectional area lesser than that of the shoulder. In the same embodiment, the implement has, at the first end, a female portion comprising a reducing taper extending inwardly from the first end, a shoulder portion extending from the taper, and a threaded portion extending further inward from the shoulder.

A handheld implement with a replaceable work tool includes a handle body which is equipped with a locking device for detachably mounting the work tool. The locking device includes a movable member, at least one retaining member and a first spring. The first spring abuts against the retaining member so that the retaining member is inserted into a locking hole of the work tool while remaining in an extended state. The retaining member includes a first mating body including at least one second mating body. The second mating body includes a mating portion, and the movable member performs translational movement so that the mating portion and the first mating body cooperate with each other to drive the retaining member to retreat and then withdraw from the locking hole of the work tool.

An improved raking device comprising extendable rake heads for raking granular material.

Farming tool systems may include a handle shaft and a farming tool that detachably connects to the handle shaft via a locking bit and a locking port that includes a socket. In some embodiments, a multi-head attachment may include one or more farming tools that slide laterally along a rail (perpendicular to the shaft length) and another farming tool that does not slide along the rail. In some embodiments, the farming tool(s) is a hoe. The farming tool(s) may be in the form of a wire that includes flat portions located inside a crimp to prevent the wire from rotating within the crimp and a forward portion that may be, for example, generally triangular in shape.

A histology radius blade grossing knife is provided. The histology radius blade grossing knife has a blade mounting system adapted to operatively retain a histology radius trimming blade. The blade mounting system provides a retaining spine for engaging an upper edge of the trimming blade, wherein a rear portion of the retaining spine is securely sandwiched by retaining plates of the blade mounting system. Furthermore, the trimming blade provides notches and/or recesses for facilitating such operative association. Each histology radius trimming blade embodies a radiused or otherwise uniquely shaped heel for cutting and dissecting tissue.

While the described shovel can include any suitable component, in some cases, it includes a blade, a shaft, a handle, a handgrip, and/or a coupling component. In some cases, the handgrip is located at a center of weight of the shovel, with substantially half of the shovel's weight distributed on each side of the handgrip. In some cases, the shaft is oriented at an angle relative to the blade and the handle is oriented at an angle relative to the shaft. In some cases, the coupling component is located along the shaft and is configured to selectively and removably connect at least a first modular section of the shaft to a second modular section of the shaft. In some cases, the coupling component is configured to only fully engage when the first and second modular sections are in a single orientation with respect to each other. Other implementations are described.
