YES! and C-clamps, basically anything that can put a strong grip on one or more objects without the use of other tools (except maybe the screw driver now used as a handle for said clamp)

My other one would definitely be the sharpie. It is much better to mark a piece prior to cutting it than to say eh, that looks good, cut it at least 3 times and it still be too short.
