A sheet binding system wherein a first post member

comprising a flat head with a hollow cylindrical shank is
adapted for insertion into a pre-punched hole in a stack
of sheets. A second cooperating post member comprising a
head with a solid cylindrical stem is adapted for an
interference fit into the hollow stem of the first post.

After clamping of the sheet stack and insertion of the
first member, suitable knife means are provided to shear
off the excess lengths of both the first and second
members to allow subsequent insertion of the second
member into the first member to provide a semi-permanent
post binding.
