[Citroënbender]

I once put a 50mm angled chisel on an Ozito rotary hammer, over a fortnight dug literally metres of pipe trench in hard shaly clay (restricted access, no room to swing a hand tool), punched through a bit of concrete footing and it was still in good working condition. Compared favourably with the hired (brand name) core drill that could barely chop out a Ø5” hole in extruded brick footings and tried to electrocute me in the process.
