super blunt

Well funny how things change the following picture is a super blunt chisel, We used to throw them away when they got to this stage now we buy them like this. Why ? Well modern machines have so much power that the blunt chisel transmits all the force into the work piece. where a chisel would chip a piece off and you would have to tee the piece up again the super blunt shatters the whole piece. This reduces the wear and tear on the breaker very significantly as the chisel does not keep slipping off and misfiring so a very significant improvement, Why i did not think of it i will never know
