Im looking into getting a Gen 4 Delica. I have the older model and it is a good blade. However, the thing that I like least about that knife is that its opening and closing action is slow and not all that smooth. Can anyone tell me if the Gen 4 is any smoother, faster, or easier to open? I know that the Gen 4 has bronze washers and I thought maybe that helped but I dont know and I havent handled one yet.
