Review: The best for Beginners like me, worth the price! - It is best for beginners. Very good quality,i have accidentally dropped it 4-5 times doing tricks on floor but not even a scratch! It has lock for not accidentally opening it. But you need to put some machine oil or simple oil to make it more sufficient in doing tricks. Just 2 drops of machine oil on each of the bearings made it more smooth. Without putting it you would have some problem flipping it.but overall it's best for it's price. Definitely recommend for beginners and pro too. You can check the photos and video i shared. I also did a Y2K trick in the video to let you know it can perform tricks.
Review: Decent balisong - It does its job but it definitely needs some lube to flip it smoothly. I applied some silicone oil which I use for Rubik’s cubes and that made it much better. The rainbow finish looks really nice. It’s almost as if it’s a skin straight from CSGO. If you’re a complete beginner I’d recommend getting a plastic trainer instead because metallic balisongs like this one are pretty heavy and your knuckles will pay the price. I’ll update this review in the future if it has some durability issues

## Features

- BEGINNER SAFETY ENGINEERING: Featuring a completely unsharpened 420J2 stainless steel blade with rounded edges and blunt tip, this trainer eliminates cutting risks during practice. The design replicates authentic weight and balance while ensuring maximum safety for mastering basic flipping techniques and advanced maneuvers.
- PRECISION PIVOT MECHANISM: Engineered with phosphor bronze bushings and adjustable pivot screws, the trainer provides smooth, consistent rotation throughout flipping sequences. The tuned action enables proper muscle memory development for aerials, rolls, and transfers without blade-related hazards.
- SECURE CLOSURE SYSTEM: Incorporating a silicone O-ring latch with positive locking engagement, the design prevents accidental openings during carry while allowing single-handed operation. The corrosion-resistant ring maintains reliable tension through repeated use cycles.

The materials resist corrosion and maintain tight tolerances for consistent performance over extended practice sessions.
- SKILL DEVELOPMENT PLATFORM: Validated for fundamental to intermediate balisong techniques, this tool supports progressive skill acquisition through safe repetition. The balanced weight distribution (60: 40 handle-to-blade ratio) ensures proper flipping dynamics while building confidence before transitioning to live blades.
