Staples seem like a good idea, until you have to remove them. Maybe you’re breaking down boxes in the shipping department, or you’re undoing some work by a carpenter who apparently was paid by the staple; you can use several different tools, but why not use a tool actually designed for the task?
Stanley-Bostitch constructs their G27W heavy-duty staple remover entirely from metal — no plastic parts here — then they plate it with a nickel finish. They specifically claim the tool can be used for heavy duty paper staples and wide crown staples, but removers like these can be used on many different types of staples.
Pricing runs about $10 for this particular staple remover.
