Assembly Instructions Product Description Did your stock Benchmade Necron spacers crack on concrete? Never fear, Zippy is here. These Zippy spacers are shatter-proof extensions that will protect your handles with no risk of cracking on hard-drops. They are available in 3x different lengths with removable tungsten weights for a more granular balance and length customization. They also offer positive jimping for extra grip, and install easily in just a few minutes (watch the assembly video above!). These spacers enable reduced handle-bias for the Necron and are a no-nonsense upgrade. Features Three different length extensions enable handle lengths of 5.3", 5.5", and 5.67" (5.67" are the length of the stock spacers), enabling you to find the perfect length to suit your preference. Protects your handles from hard drops: Spacers are made from a shatter-proof polyurethane that won't crack on concrete like the stock spacers. Adjustable balance: Each spacer houses up to 2x removable Tungsten weights which enable you to find the perfect balance to suit your preference. The Zippy balance system is 6x more granular than the stock system (for example, the Zippy system lets you add/remove weight from each handle in 0.022 oz increments, compared to the stock tungsten disks which require you to add/remove in 0.124 oz increments to maintain handle symmetry). For comparison, a stock BRS Replicant Titanium spacer weighs 0.110 oz, which highlights how the stock Necron weight system provides far too much handle bias for competitive flipping. The higher granularity of the Zippy system offers more "flippable" configurations. Compatible with both trainer and live blade. Positive "sawtooth" jimping for extra grip on ladders and chokers.
