Here is basically what I carry, 1/4", 3/8", and 1/2" sockets and ratchets, both metric and imperial, combination wrenches both metric and imperial, misc sockets and such as mentioned above (torx, 36 mm, flare wrenches), an assortment of screwdrivers and pliers, vise-grips, duct tape. That about covers the major things I carry.
