Forward Controls Design CNP Castle Nut Punch

Machined from D2 steel, heat treated and finished in black oxide, CNP has a broad / flared top to provide a stable striking surface.  It also has widely spaced and aggressive serrations to ensure the user’s hands, gloved or ungloved, will not lose their grip.

CNP was originally designed to have a rectangular tip, it was subsequently abandoned, and we went to a round tip.  A rectangular tip can be very unforgiving of tip placement, and the sharp edge and corners of a rectangular tip can be rapidly and more easily deformed and most importantly, we don’t see any advantage of a square stake over a round stake a conventional punch produces.  Given the host of problems a rectangular tip has and what it brings to the table (nothing), it was an easy decision to redesign CNP to have a round tip.

We produced a handful of candidate tips with different sharpness and angles, and decided on 52.5 degrees angle with a sharp tip.  Each prototype was tested for ease of use, and effectiveness of the angle and sharpness.  The design also changed from a rather long and larger diameter body to one with a shorter length smaller diameter.  With the original design, we believed the larger contact area would obviate the need for serrations.  Since the redesign now has a smaller diameter, serrations were added to provide positive grip on the CNP.
