A tool assembly includes an elongated handle and a locking system for attaching a tool head to the handle. The tool head can be a floor care tool or other accessory that can be attached to the handle such that the elongated length of the handle can aid in the use of the tool attached. The locking system includes a keyed locking collar for engaging at least a first portion of the tool head, and a locking cap rotatably positioned on the handle for engaging a second portion of the tool head. The handle can be extendable, such as by telescoping, and can also be overmolded.

A tool head for easy attachment and detachment to a handle is provided for configurations such as axes, picks, shovels, sledges, hatches, and hoes. The tool head includes two clamps, one clamp being threadingly engaged on a shaft that freely rotates within the tool head. To attach the tool head to a handle, the user rotates the shaft which moves the clamps together and compresses the handle there between first clamp moves towards a second clamp. To detach, the shaft is counter rotated thereby decompressing the handle. When detached from a handle, the clamps turn and nest in two cutouts within the tool head allowing for compact storage or packing. Integrally formed features that include scraper, blade, wrenches, gut hook, cord cutter, carabineer, and the like provide the user in the field needed tools when fashioning a handle from a sapling or stick.

An adjustable tool holder is configured for interchangeable use with a variety of tools provided with different connection elements. The connection elements include at least a first connection element configured for a first manner of connection with the tool holder and a second connection element configured for a second manner of connection with the tool holder. The tool holder includes a distally extending tool support operable to detachably support each of the tools. The tool support includes a first tool connector configured to releasably connect with the first connection element in the first manner of connection. The tool support includes a second tool connector configured to releasably connect with the second connection element in the second manner of connection.

A ring handle for a craft knife that is configured to securely hold a cutting blade by forming a friction fit with the cutting blade and without engaging with a hole or notch in the cutting blade. The craft knife handle includes a blade slot recess that is formed with a ridge or tapered section that is adapted to abut with the edges of the cutting blade that are inserted into the blade slot. The craft knife handle also includes a collar that engages with the handle body of the craft knife handle to secure the cutting blade within the blade slot. The craft knife handle may also incorporate a no-roll design with at least one facet of the handle being flat.

A hand tool with a replaceable workpiece head includes a handle and a workpiece head. A rear end of the workpiece head is provided with an insertion block. A front end surface of the handle is provided with an insertion hole. The insertion block of the workpiece head is inserted into the insertion hole. A side wall of the handle is provided with a receiving slot which is communicated with the insertion hole. A rear end of the insertion block is provided with a locking part. The receiving slot is provided with a movable locking member and a pushing mechanism. The pushing mechanism is capable of pushing the movable locking member such that the movable locking member and the locking part are engaged with each other.

A file handle has a body, a ferrule, a clamping assembly, and a cap. The body has a first end and a second end opposite to the first end. The ferrule is assembled at the first assembling end of the body. The clamping assembly is movably mounted in the body and has two clamping portions and a threaded hole. The two clamping portions extend through the ferrule. The two clamping portions are subjected to an elastic force and oppositely separated from each other. The threaded hole is adjacent to the second assembling end of the body. The cap is rotatably assembled at the second assembling end of the body and has a screwing stick screwed in the threaded hole. Because the space between the two clamping portions can be adjusted by turning the cap, a user can clamp a tang of a file blade by the file handle.
