Wiha - I use their screwdrivers as they are comfortable, decent long shafts, good quality tips that take a bit of abuse. I have a couple of standard sets and a slimfix set.
Knipex - I use their cutters, pliers, and pipe grips. Very good quality tools that stay sharp for years and never suffer from hinge wobble.
Bahco - The go to brand for adjustable spanners. Good smooth movement, nice tight grip, and don't suffer from age related slackness. I also have bahco croppers and hacksaw but they are much of a muchnes.
Milwaukee - Combi drill, SDS, circular saw, battery driver, led torch. Great quality gear that keeps on going with plenty of grunt. The batteries are also great and have no noticeable drop in performance 4 years down the line. My combi suffered a blown PCB after 4 years, outside it's 3 year warranty, but a local shop provided a new handle, trigger, PCB, battery connector, and brush ring, (basically everything apart from the motor, gearbox, and chuck) for £50 fitted.
They also have a new 9.0Ah battery out !!!! I'll be waiting until silly prices subside though.
