Abstract
A steel rule die has a die base of deformable material with a slit cut therein. A steel rule forms a die punch having a base portion insertable into the slit. Spaced projections are arranged around an outer face said base portion such that upon insertion of the die punch into the slit the projections extend into locking engagement with the die base to inhibit extraction of the die punch from the die base.
