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.

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.
