I just did an essay on this but I want to write more about it. Wait a second. Let me find it. Where is my butterfly knife? I'm going to run upstairs. GOT IT! So if you want to learn more about butterfly knives I would recommend looking up tricks on YouTube or just on Google. I'm going to try to learn a new trick some time this week so I can get really good at it. I want to get another one and maybe if I'm really pro with this one my parents will let me get a new one. The one I have now is pretty bad and held together with masking tape. A new one after my second testing makes sense since I got the first one after the first testing.
