According to the present invention in the form
illustrated in Figs. 1, 2 and 3, the supporting

these jaws are made of a corrosion-resistant
sheet material such as stainless steel. Thus the
useful life of the tool of this invention will be
comparatively long.

For the purpose of cleaning the surface of‘the

of metal therefrom, the jaws l9 and 20 are'pro
vided'on their inner surfaces with abrasive ma

or other suitable sheet abrasive material, the
edges of the cloth being held by folding over in
wardly the vertical edges 26 and 21} of the jaws
respectively to clamp said edges.
