ABSTRACT:
A tool primarily for pulling stakes from concrete forms includes a relatively long lever arm and a bore for encircling a metal stake, oriented generally at right angles to the lever arm. In preferred embodiments, the bore has a relatively sharp edge and gripping teeth for positive gripping engagement against the rod to enable twisting of the stake and subsequent lifting of the stake. The tool also includes, in preferred embodiments, a protruding fulcrum end to allow prying the stake up using the stationary wooden form for engagement by the fulcrum point. A further preferred feature is a chisel edge on the fulcrum end, to enable the tool to be used for form stripping. The chisel end may further include an opening configured for nail pulling. Thus, in a preferred embodiment the tool can be used for nail removal from forms, for stake twisting and pulling, for stripping of forms from concrete and also for bending of reinforcing bar to a substantially accurate, consistent bend angle. One preferred but optionally further feature is that the long lever is hollow through most of its length, enabling it to be used for straightening stakes that have been bent in the driving or removal process.
