Crucible Industries' S35VN steel substitutes niobium carbides for some of the vanadium in their popular S30V steel. They estimate this steel to be 15-20% tougher than S30V without any loss of wear resistance—it's improved toughness gives it better resistance to edge chipping. This steel has gained rapid popularity with both custom knifemakers and the steel aficionados who make up a good chunk of your customers.
The G-10 handle is narrowed at the end improving the ergonomics. The handle and blade have been profiled thinner; removing uncomfortable angles when in the closed position. It features a Compression Lock and an ambidextrous-friendly four way clip which carries tip-up/tip-down, left/right-hand and rests deeper in a pocket. Spyderco kept the same full flat-ground blade but they've also lengthened the blade's tip and added additional surface jimping to both the spine and finger choil. Implementation of a Bushing Pivot System generates fluid action and more consistent manufacturing tolerances. Larger lanyard gives more options for carry.
