How can i tell if a Butterfly Knife is of good quality?

Nothing like brands or anything. I just wanna know how to tell if a Balisong ( Butterfly Knife ) is good quality no matter who made it.|||Check the build quality. Is the blade finished to a High standard- For example is the blade edge ground evenly? Does the handle wobble? Is there any play in the pivots? Are the edges on the handles rounded? Is the name of the blade steel stamped into the blade along the hilt? - Fro Example 420HC, 420J.





Check for these simple things, and other things/issues which might effect the use of you balisong.
