This vintage turnscrew is a heavy-duty screwdriver manufactured by W. H. Clay Ltd in Sheffield, England, a firm renowned for high-quality edge tools during the mid-20th century. Dating to approximately the 1940s or 1950s, this tool is a testament to British industrial craftsmanship. It features a classic oval-shaped wooden handle designed for a comfortable, firm grip when applying significant torque to large screws.
The steel blade, which measures 37 x 5cm, includes a flared "waist" that provided extra strength for demanding cabinet making and joinery tasks. The maker’s stamp and registered design number 9015855 remain visible on the shaft. The tool is in overall good vintage condition, structurally sound with cosmetic wear and patina due to age.
This authentic Sheffield piece would suit a collector of traditional hand tools or a craftsman who appreciates the durability of mid-century workshop equipment.
