For safety - you should remove all that 'mushroom' from the top of that chisel.........

It's not my photograph (or chisel!) - knicked the picture from a Land Rover forum.
Our of interest, why is this safer? Are the edges of the mushroom liable to fracture and blow off?

YES
The mushrooming/overhanging metal should be kept trimmed off by grinding as it is likely to cause a false blow and so damage the hand or splinter and cause injury to your body especially your eyes.
See the attached for how chisels should be finished[frame][/frame]

The above was taken from hand book 'Bench Work and fitting ' by W.J Peck M.Eng., M.I.Mech.E. Published by Pitman. A very good book and covers the majority of basic workshop practice.

Oo, that's going on the 'to buy' list, thanks.

And by the way - The lump hammer, the head is just about to fall off and if used like that could fly off and do serious damage to someone and/or cause a nasty dent in ones vehicle.
I do not think that the person using the tools has read any book on workshop practice
Happy motoring.

I seem to recall a bloke on a Landrover forum dying from a blow to the head from a heavy metal object and shrapnel in the eyes.

I recall someone saying that could happen!

I was once sent on a visit to the HSE museum of horrors (industrial accidents) in London and it was not very nice especially the scalp of real hair from a young woman caught in a radial drill; all there to see; and the pickled amputated hands covered in dermatitis.
It certainly made me aware of what can happen when the correct procedures/safety equipment are not used.
Whilst light can be made of the chisel and hammer they can be deadly if not used and maintained properly.
