The staple-free stapler isn't a new idea; they've been around for decades, locking pages together without the need for tiny metal clips. But older designs use a method where an unsightly hole is punched through your documents, unlike Kokuyo's clever new Harinacs stapler which simply crimps the corners to keep up to five pages securely attached to each other.
The $10 stapler uses a set of serrated metal teeth to pressure bond the corners of documents together, but it's not a permanent seal. Simply rubbing the bonded area with a hard object like a pen cap smooths out the crinkles and releases the documents without having to reach for the steel jaws of a staple remover.
