on some knives i have noticed that the finish that they put on the metal (be it a DLC or similar coating or just plain beadblasted) can give it that texture and feel. TI is so light as it is, if the finish is a certain way it could definatily come off as a plastic like feel. not the most common thing, but it has happened. if you were to scratch that side up, you would see it to be metal definatly.
kinda weird how finishes do that.
ah i know what you mean now, cheers!
