This was the first full knife blade I ever designed and I am happy to say it is one of the sharpest knives I have ever handled. I patterned the blade to retain some of the fundamental design cues of SOG’s past while at the same time incorporating functional design elements that would improve the cutting function of the knife. From the empirical and theoretical research I had done on serrations I learned that a smooth undulating transverse motion would yield the most effortless cut. I calculated out a smooth undulation, which became the belly of the blade. Since I have long fingers I have always found the thumb grip area on most knives to be uncomfortable and small, so I lengthened out the jimping and added a slight recurve so that my thumb would comfortably fit.
Assisted knives are notoriously complicated. Compound that with having to fit the mechanism into a single folded piece of sheet metal and you have the Slim Jim

Patent Pending on this assisted knife mechanism. If awarded I will get to join the club of only 4 other inventors in the world with an assisted knife patent.
It is too bad the handles aren't transparent since the mechanism is a fun physics mind bender.
