First knife of the newish year

[Hanzo Kendo]

First finished piece of 2011. Took more care into bevel this time. I like the look and feel of the subtle concave bevels, but I really need to master the hallow grind. Tried my hand at engraving with this one, used a dremel diamond bit. IT worked, but didn't feel as smooth as I would think a more professional bit would, any suggestions? Did engrave a makers mark, it looks like crap, but its there. I have seen some of you guys using chem/electric gadgets for adding your mark, any suggestions for making/ordering a stamp style one?

Thanks for looking.
