Irazola screwdrivers, dont buy the set just what you need as some you wont ever use.
Knipex snips, pliers if you require them.
Glanding spanners (using footprints or water pump pliers is just rough IMHO)
Voltage tester or fluke rms tester if your doing more industrial jobs.
Hacksaw, jnr hacksaw, allan keys, tape measure and torch.
If working industrial buy a croning tool, 17,19,21 spanners and crimping tool (ratchet type)
If working domestically buy wood saw, floor lifter (bolster works quite well), scotch hammer for raggling, cold chisel, pad saw for cutting out gyproc, holesaw sets for cutting in downlighters and a battery drill.
I thought that knipex were th best after looking around myself, so in th screwfix catalogue there are several types, the com bination pliers, long nose pliers, wite strippers and th cable shears also where would I be able to but that tool which cuts the armoured cable to strip it?
sorry i dont know the name of it
Stanley knife and jnr hacksaw.
Anything else is a waste of time.
