I have ADHD which makes me fidget a lot. Not great when you are trying to sit still at work or even watch a movie on TV. This butterfly knife trainer by Anlado makes a great fidget object. There is no blade so you can’t accidentally hurt yourself.
On another note, for those looking to learn to flip a butterfly knife, this is a great way to train.
This product is made of enhanced stainless steel. It is durable and won’t rust.
