Description The Squidtrainer was the first balisong trainer to be produced by Squid Industries.  Since its inception in 2015, we’ve integrated feedback from flippers all around the world each year to make it the best flipper in its class.  The Squidtrainer V4 has undergone significant change since the first production run in 2016. It features the following: Integral channel handle design machined from 6061 T6511 aluminum alloy Machined handle texture pattern and bead blast finish for better grip Rounded handles and blade spine for enhanced comfort and durability Precision ground heat treated 410 stainless blade for maximum smoothness, minimal handle play, and zero blade rub Press-fit stainless steel rods installed into the ends of each handle for better feel and momentum In November 2022, we unveiled the V4 which added the following upgrades: 416 stainless steel bushings tuned to each blade for the best tolerances Jimping added to the ends of each handle for increased grip and stability *Actual product colors may vary due to monitor settings and photograph lighting.  Manufactured and assembled in the USA Specifications Total Length (Open Position) 10" Total Length (Closed Position) 5.75" Handle Length 5.5" Handle Thickness 0.5" Blade Length 5.2" Weight 4.6 Ounces Handle Material 6061 T6511 Aluminum Handle Finish Milled Texture, Bead Blasted  Blade Material 410 Heat Treated Stainless Steel Blade Finish Stonewash Pin Design Zen Pins Handle Design Channel Pivot Design Bushings  Latch Design Latchless Balance Profile Neutral Each and every Squid Industries balisong is hand-assembled and tested to ensure that each unit is an exceptional flipper. All Squid Industries Balisongs arrive with a box, microfiber pouch, and sticker.
