Take an old pair of very thick wool socks

your hand, letting your thumb stick out
through the hole in the heel. Cut the toes
off at your knuckles.

It helps a lot, particularly if the leg
covers most of your forearm. I can knit and
type wearing "wristers"; wrenches should not
be a problem. (Though mine were
a closer-fitting custom-knitted pair.)

I have "torghandlarhandskar" (literally square
seller gloves) which are gloves with cut ends
at the fingertips. But the forearm stuff was
new to me. I have many Merino wool socks so one
of them would be optimal, I think.
