Hi all.I'm thinking of picking up a M16-13T.But I'm a little confused about the blade grind on this knife.I've read in past posts that the serrated blades are only sharpened on one side?I know what a chisel grind is,whats the difference between these two?Does it make any practical difference in cutting ability?Also,are the non serrated blades ground the same way.Thanks to anyone who can help.
