Twosun are great value knives. I own three of them. 2 titanium frame locks and a g10 version. I had another ti but when i showed it to my buddy he insisted i sell it to him! They are razor sharp, fit and bearing action are great, materials are great. finishes can be less than perfect sometimes with some scratches, sharp edges ,or marrs occasionally but you cannot beat them for the money. where can you buy a nice titanium frame lock with the d2 steel for under 50 bucks ? They also offer m390 verSions for about $100. Overall a nice piece that can be beat on and not afraid about scratches or losing it.
