What a beautiful saw! I had an Adria dovetail saw that looked similar and it was pure pleasure to use. I don't cut dovetails by hand anymore, preferring instead the incra system for the router. In case you may not have heard about it, I will pass on a really great resource from a true master of hand tools. Frank Klausz has some very good videos that he did for Taunton. Hand Tools shows among other things how to sharpen and set the teeth on the hand saw. How To Dovetail a Drawer has some great tips if you want to pursue the hand tool thing towards mastery. Highly recommended--watching him work is about as good as it gets for this type of woodworking.
