Looks nice and very functional too !
About the handle - if you want plain white handles, consider Dupont Corian. There's outfit on the Web that sells smaller pieces in just the right thickness. Somewhere in upstate NY methinks. Very inexpensive.
About hand rubbed blade finish - looks like you used too coarse of abrasive. Normally, "scratch" lines are parallel to the lengthwise direction of the knife and don't curve . If u clamp the blade down, you can fashion a simple "guide" by clamping down next to it a piece of wood. Before hand-rubbing, the blade still has to be polished to mirror finish.
