DEwing,
Nice looking knife. It seems you have quite a bit of thickness all the way down the spine. In the future you might try tapering the blade as it goes towards the tip. It looks nice, helps with the balance and feel in the hand as well as reducing weight. Some naturally occurring taper happens when your grind line runs parallel to your cutting edge. You have a lot of spine thickness because you ran the grind fairly straight down to the tip. For knife #3 though, this is very good.
