Squid Industries Squidtrainer V4 Butterfly Balisong Trainer Black (4.5" SW)


  • 410 Stainless steel blade heat treated and stonewashed for a tough and durable blade.
  • Phosphorus bronze washers provide ultra-smooth flipping action.
  • Channel constructed black aluminum handles are strong, lightweight, and subtly textured for a sure grip.
  • Improved machining tolerances provide maximum smoothness, minimal handle play, and zero blade tap.


Since it's release in 2016, the Squidtrainer has been amazingly popular among bali flippers, but Squid Industries has continued to upgrade the design to make it better and better. The V3.5 features more rounded edges, a cleaner blade finish, a textured handle pattern, and tighter machining tolerances.

Customer Reviews

This is amazing
James N. on Feb 11, 2022

I have a couple very nice balisongs, and have been using a couple less expensive trainers. I have looked at the Squid Industries products for a couple years. I would watch their weekly product drops, and see them completely sell out immediately, and figured they must be good. I finally ordered a Squid Trainer 3.5. If you're on the fence about this because of the price - This thing will put your soul at ease the instant it's in your hand. This makes other trainers look and feel like trash. Just buy it. The End.
