YF Butterfly Training Knife Practice Knife Trainer Dull Butterfly Trainer Comb Matte Black Finished Stainless Steel Flick for Easy Safety Folding Flip for Sport Hiking Outdoor Indoor 8.9-Inch Overall

The screws are really tight when you get it but it works as a comb well :)

This trainer is great. In two days, I managed to be able to open and close in a normal fast manner. It also functional thanks to the add on of the comb. The material is all metal, so durability is strong. Compared to others similar to this, this was the cheapest option I found and the best thing I did. Thanks to this, I’m now experimenting show off tricks for me to master before potentially getting a butterfly knife. Great product overall.

It was a little hard to get open and to relive. But it is a great trainer and solidly built

It's a pretty decent product holds together well. But at the same time I dont flip it as I use it as a comb.

It was ok but it broke in the first few days wouldn’t really recommend. But it’s OK if you take care of it

Definitely worth your money. Comb is a strong metal and the flexibility/dexterity of the handles are smooth. Good for beginners and for styling.

This is a really cool practice butterfly comb. Its a mix of unique and old style. It's the perfect weight to practice. The comb makes it functional as well.Perfect gift for collectors!

Exactly what my so wanted but it came as a box of like 20 individually packaged ones.
