Inked Series Squidtrainer V3.5

Regular price $169.99 Sale


The Squidtrainer was first released in early 2016 to create an affordable and high quality flipper. With each passing year, we integrated feedback from flippers all around the world into the design to make it the best flipping experience possible. Upgrades that weren't utilized before such as the crowned spine and heat treated stainless steel blade are now standard features that you'll find on the Squidtrainer. As part of our ongoing mission to constantly improve our products, we're releasing our latest version--the V3.5. The changes are as follows:
  • Upgraded the bead blast and handle texture pattern for better grip
  • Fully rounded the bottom edges of the handles for enhanced comfort and durability
  • Changed the stonewash to a cleaner, classier, and cooler style 
  • Improved machining tolerances for maximum smoothness, minimal handle play, and zero tap

The new Inked Series Squidtrainer V3.5 features a DLC coated blade.
