Good set of Torx wrenches
A while back I bought a set of Torx wrenches that appeared to be very high quality but turned out to be very soft and ended up being stripped easily. They also didn't fit too well into Torx bolt heads. In fact, my Torx key multitool has much better quality wrenches on it!
What I'm after are a set of workshop Torx wrenches that are double ended and can get into awkward spaces (i.e. L-shaped with a wrench at each end of the 'L"). I'm in the UK by the way so would prefer to source locally. I need sizes up to T55 at least.
