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

This Squidtrainer V3.5 model has a silver finished aluminum handle and a stonewashed trainer blade.

Since it's release in 2016, the Squidtrainer has been amazingly popular among bali flippers, but Squid Industires 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.


  • Channel constructed 6061 T6511 aluminum handles are strong, lightweight, and subtly textured for a sure grip.
  • 410 Stainless steel blade heat treated and stonewashed for a tough and durable blade.
  • Phosphorus bronze washers provide ultra-smooth flipping action.
  • Improved machining tolerances provide maximum smoothness, minimal handle play, and zero blade tap.
  • Crowned spine adds significant comfort during tricks like rollovers and chaplins.

Customer Reviews

love it
Ryeland W. on Apr 13, 2021

had it for two weeks flips insanely well, i was surprised as to how good it flips. 10/10 your able to toon it to the point where there's no tap almost no play and still great swing.

Love to flip this thing
Ryan L. on Jan 19, 2018

It is light but balanced and it is my main flipper as it can take a beating. The texture makes gripping surprisingly good, as it doesnt fly out of my hand as much as a triton which has smooth Aluminum handles.

Best trainer for the price!

This trainer is probably the best for under $200. It feels, sounds, and flips great! Lucas Cao, the creator, really knows what he's doing. The little "bite side indicator" on the blade really helps remind you when you're on the wrong side. I only have 2 complaints about this product: 1) The knife can take a beating, and it's perfect for EDC, but the handles do dent fairly easily because they're aluminum. 2) This isn't really a complaint about the product, just on how easy it is to obtain. When you want to get a squid, they are almost impossible. I don't know how I got mine. The drops sell out almost instantly. If you're up to date and you know what your're doing, you should be able to snag one eventually. Happy Flipping! -HT

Great trainer
Jonathan G. on Oct 19, 2017

I ordered from the first batch that was released. Cool to see Squid on BHQ. Flips great right out of the box. I like the weight and the length. Price is great, too. I usually flip live, so I also like the bump at the base of the "live" edge - if I try to chap on that side, it's a little reminder. The blade has a subtle audible ring every now and then that I quite like. The other trainers I've flipped are CCCs and the BM 62T, which I don't like at all. Watch your screws and do regular maintenance - I needed to reapply a threadlocker after about two weeks of pretty heavy flipping. Hasn't come loose again since. This shouldn't be new information to a flipper, but if you're just starting out, do yourself a favor and pick up some threadlocker, or check out Squid's site, I think he sells a maintenance kit too. Oh, on that note, check out Squid's Youtube channel, he posts some really good tutorials. The only thing that took a second to get used to was how square the handles are. This isn't a complaint (the edges are rounded, so it's still quite comfortable), it just took me a minute with certain moves, like Choker fanning. I carry mine around all over the place.

Hard to get- worth every penny.

Tolerances are tight right out of the box and it flips like a dream. It literally sings every time the blade and handles clack together. A great find.
