ABSTRACT:
A chisel 1, 2, for removing hard deposits 29 inside a chimney 14, which is braced against one wall 24 to exert a chiseling force on the opposite wall 23. The chisel 1, 2 is sharp on one end 22 and is manipulated by a pushing handle 6 and a pulling handle 4. The chisel 1, 2 is longer than the inside width 26 of the chimney 14 so that a pushing force 19 and a pulling force 20 causes the sharp end 22 to dig into the deposits 29. By exerting slightly more pushing force 19 than pulling force 20 the chisel 1, 2 is made to move along the walls 23, 24 chiseling deposits 29 off as it goes.
