摘要:
The invention relates to hand tools, particularly garden tools, such as for example garden spades, garden forks and the like. Such tools are known to have a fully forged operative end with an integral socket for connection to a handle. They have high strength but are expensive and require high levels of operator skills in their manufacture. Fabricated constructions from pressings deduce noticeably costs of production but at the expense of strength. The object of the invention is to provide such hand tools that have both acceptable cost factors and acceptable levels of strength. The objective is met by a construction comprising a blade/prong portion (9,22), a separately formed and forged frog (1,13), said separately formed and forged frog (1,13) being suitably secured e.g. by welding, to the blade/prong portion (9,22) and to a separately formed socket (10,21) for connection to a handle.
