Tac Force TF-428W Satin 3.5" Blade Pakkawood Handle, Assisted Opening
[TF428W]

It is a bit hard to open with one hand and if you do, the blade get stuck (the metal part that lock the blade goes too far and you can't unlock it unless you use a tool). So it feels like a lockback knife. Also, when the part goes too far, the blade isn't completly locked.
