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.

Abstract: A frame-supported vehicle, such as a bicycle or the like, has at least one frame component made of a light diffusing or fluorescent translucent or transparent material to form a leaky light pipe, and at least one light source in light communication with the frame component, whereby light propagates within the frame and is visible from outside the frame by diffusion or fluorescence or a combination thereof. The bicycle is highly visible at night, and may carry logos or other indicia that are enhanced by the background illumination, which may be redirected out of the tube. The frame component may be load bearing or non load bearing. In the latter case, it may be provided as an add-on accessory.
