Which trainer should I buy?

If you're new to balisong/ butterfly knife flipping or would like to introduce balisong/ butterfly knife flipping to a friend, we recommend the Squiddy, Squiddy-B, or Squiddy-U which are great for people of all ages and skill levels. If you want to become a pro balisong/ butterfly knife flipper, we recommend the Mako, Triton, Squidtrainer, or Nautilus. All of our options are equal in terms of flipping, but the higher priced models have higher build quality which results in better handle play, smoother action, and higher durability. 

What's the difference between the Squiddy, Squiddy-B, and Squiddy-U?

The Squiddy is made of CPVC material, but does not have the weighted nose pin like the Squiddy-B or Squiddy-U. Both the Squiddy-B and Squiddy-U are made of the same material, Acetal, an engineering thermoplastic used in precision parts. This material is provides more durability. On top of that, they both have a weighted nose pin and silencing mod, which provides a better weight balance and noise reduction when flipping!

What's the difference between the Mako, Triton, and Squidtrainer V3.5?

All three of these trainers use 6061-T651 aircraft grade aluminum handles. Both the Mako and Triton utilize a 304 stainless steel trainer blade, but the Mako uses a sandwich handle design whereas the Triton uses a channel handle design (sandwich is two connected pieces whereas channel is one solid piece). The channel design offers higher durability over the sandwich design. 

The Squidtrainer V3.5 uses a channel handle design in addition to an extremely durable heat treated 410 stainless steel trainer blade. During hard drops on surfaces like concrete or gravel, the Mako and Triton blade may bend similar to a spoon or fork (although it's very easy to straighten out with just your hands). The Squidtrainer's heat treated blade is significantly stronger and can therefore withstand much more wear and abuse without any chance of bending. Additionally, the Squidtrainer has a unique machined handle texture pattern which results in better grip. Lastly, the Squidtrainer utilizes press-fit steel rods at the ends of the handles for additional momentum and a crowned spine for more comfort during ricochets and chaplins. 

What's the difference between the Squidtrainer V3.5 and Nautilus?

Both the Squidtrainer and Nautilus use similar materials however the Nautilus handles utilize G10 overlays which enhances both durability and grip. Additionally, the Nautilus handles have a tapered profile which allows for more control around the pivot area. The Squidtrainer uses a washer pivot system whereas the Nautilus uses a bushing pivot system. The bushing pivot system produces lower handle play and smoother action. 

Both trainers exhibit phenomenal balance, but the Nautilus is lighter and has slightly more handle bias whereas the Squidtrainer is more neutrally weighted. While balance is mostly personal preference, we've found that handle biased balisongs are more commonly preferred by most beginners. 

Lastly, the Squidtrainer features a prominent and unique ring that is similar to that of a tuning fork. The Nautilus on the other hand is extremely quiet and is well suited for environments where silent flipping is necessary. 

What are blemished trainers?

Blemished balisong/ butterfly knife trainers are models that didn't pass our inspection process due to cosmetic imperfections (Scratches, dents, discolorations, etc.) but are guaranteed to flip just as well as our new products. They are offered at a discounted price under Calamari Clearance.


How do I keep my trainer maintained?

In order to keep your balisong/ butterfly knife trainer maintained, you'll first need a Balisong Maintenance Kit.

The T10 torx driver is just like any other screw driver--just make sure that you're keeping it perpendicular to your trainer and fully inserted so that it doesn't slip and strip screw. If you find that the pivots are spinning as you are unscrewing the pivot screws, you can squeeze the handles together in closed position to prevent them from moving. For a more detailed tutorial, read our blog post on "How to Fix Spinning Pivots."

The Loctite 243 is a threadlocker which prevents the screws from coming out. It should be used anytime you take apart your balisong or find that the screws are starting to work their way out of your trainer. Apply about half a rice grain worth onto the threads of the screws (the spirally part beneath the screw head). Try your best to clean out the old loctite before applying a new layer. You can do this by using some sort of pointed object to push it out or by submerging the screw and/or pivot in alcohol or acetone. You should wait a minimum of 12 hours before using your balisong after you've applied the loctite.

The lubricant can be applied at any time whenever you think it's necessary such as if the trainer is moving too slowly. Holding your balisong upright in closed position, drip a small drop onto the top of each washer and blow onto it to get the lubricant to move down and around the washers.

What kind of Torx driver do I need?

All of our products require a T10 torx driver for disassembly and arrive thread locked. The thread locker may cause the pivots to freely spin during disassembly, preventing you from removing the screws. To counter this, squeeze the handles tightly together as you turn your torx driver.

One of the handles on my trainer is moving slowly. How can I make it smooth again?
