The OG product that started it all. The Squidtrainer is our flagship product and crafted for the absolute best performance. Highly acclaimed for its innovative build characteristics, the Squidtrainer continues to be a dominant and competitive balisong.


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.

Manufactured and assembled in the USA


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
