### ⭐⭐⭐⭐ After a bit of use the bite handle became weird.
*by C***Y on February 13, 2026*

It’s a great trainer balisong overall. A good weight, a good feel, good quality, though there is one problem I have with it. After about 4 days of use, the bite handle has just been weird, I don’t know how to explain it, but it’s kind of tight. Aside from that, I’d definitely recommend this knife for a first balisong.
