GREMLIN Practice Knife Trainer, Flip Training Knife With Dull Blade & G10 Handle, Flipping as smooth as butter, Great Gift For Beginner Intermediate, Comes With Screwdriver And Extra Screws. (Pink)

The bolt on the butterfly knife unscrew easily and are hard to tighten. Using thread lock should help with this, but in my case I did not have that, therefore it was unfortunate.

The screws being loose is of my own problem, seeing as I unscrewed it to remove the latch, not realizing that it was reinforced with glue, however, due to the removal of the screws, they have become very loose, and I have accidentally lost a screw while flipping, and also misplaced the extras. If someone knows what type of screws were used in the balisong, please tell me.

It works okay out of the box but I liked mine better after a bit of tuning.

My son loves to fidget with his hands and this has kept him occupied for hours and hours! Great for keeping his mind and hands occupied!

it was a great way to start using butterfly knifes for fun great for doing trick and other things its super dull so its safe and yeah no complaints

My son loves it, bought one for his friend as well

not much to say. some might find it a bit heavy. but its really cool and great way to learn tricks.

it feels like who ever assembled it wasn't doing any quality check. screws are loose and too much play between joints. Once you tighten the screws up and oil up the joints then its a acceptable practice toy. Would think I would get a better quality for the price. not the sellers fault just the manufacturer.

Unlike some of the reviews, the unit isn't pre-tuned. It arrived stiff and took a little wiggling and twisting to loosen it up. It definitely doesn't feel like it's on bearings out of the box.The screws are properly sealed with locktite though and it being only one sided screw means there's no real way to disassemble because the whole bolt just turns with the screw.
