When the block is positioned with one of such sides against a working surface, the other side is perpendicular to such surface. A longitudinally extending groove is provided in such other side in perpendicular relation to the working surface. A matnetizable nail placed in such groove is retained perpendicularly to such surface and can thereby be initially driven straight into the surface.
