DDR Knives changed the name of its recently-revealed composite blade configuration from ‘Zipper’ to ‘Fusion’ in response to a post on social media by maker Michael Walker. Walker took issue with the similarities between the DDR Knives composite construction and his own Zipper Blade style.
The DDR Knives composite pattern debuted on their AOD and new MOAB models. DDR named the pattern “Zipper” because the spine of Damascus was attached to a Stellite 6K blade with a decorative interlocking look. Walker, who has been making a signature style of knife called Zipper Blades since 1990, expressed his frustration with the similarities to his work in this social media post made yesterday:

Just what has Darrel Ralph contributed? Share if you want.
Walker, well-known as the inventor of the liner lock, patented the Zipper Blade construction in 1990 – the patent has since expired.
