G10 Multifunctional Butterfly Ruler Super Smooth Well Balanced(Green)

Screws get loose without thread lock. Wish they applied it before shipping.

This was my second trainer butterfly knife and I just use them as a great fidget toy. The first one wore down quite quickly but I've had this one for a couple years now and its only just starting to see some weakness in some of the joints with pretty much daily use and I'd bet it still has a couple years left of life even with my heavy use and very often dropping it!

It started out very smooth but with a couple of soft drops (on rubber mat/couch/grass) the bushings needed tightening. However you can't tighten it since only one side has a tool insert while the other side of the pin just free spins with no way to lock it in place. So now it's super wobbly and I cannot fix it.

HELP!!! my screw keeps coming loose. I think it's called a bushing, the things that holds the bearings in place. Can someone tell me what screw drivers they use to tighten up these practice Balisongs? Thanks

I’ve tried a bunch of trainers in this price range. This is by far my favorite. The weight is great. It’s super smooth. And all the others have come loose. Now I understand even high end knives need locktite applied. So this really isn’t major but I’ve been beating this one up for days and it’s still rock solid. I would buy it again in a second over any others I’ve tried.
