Just received packagd from AliExpress: two Sog and two Gerber MT "copies".
Sog medium nylon sheat is sturdy. I dislike belt clip (prefer classic belt loop).
Sog Sync feels like new Sog MTs (made in prc).
Gerber Curve has no logo. Locking is smooth. It is tiny and has limited usage.
Gerber Solstice is well made.
