A couple of months back, I bought two Paragon saws- a dovetail saw and a tenon saw. Relatively cheap (less than $120 for the both of them), but there were a couple of issues. First, the handles didn't fit my hands; they were way too small. So, I built a couple of new handles (Gramercy pattern) and that solved that issue. The next issue was how they were sharpened. The dovetail saw in particular, although new, seemed to cut only as well as an old Stanley gent's saw I'd been using. After reading an article by Chris Schwarz on this guy from Wisconsin (Mark Harrell of Technoprimitives), I sent the dovetail saw off to him for sharpening. Man, can that guy sharpen a saw. Night and day difference.
(Actually getting to my point here......)
When I consider the original cost of the dovetail saw, the very reasonable cost to get it sharpened correctly, and my time to build the new handles, AND from a purely economic standpoint, I'd have been better off just buying one of the Wenzloff, LN (or one of the NEW??) LV dovetail saws. Don't get me wrong, making the new saw handles was good experience. But, in the end, I'd recommend that if you're in the market for a new saw, and you don't want to take the time to fettle/otherwise modify the saw to fit you, bite the bullet and buy a good one right from the get go. (I realize the requisite and obviously applicable "penny wise and pound foolish" discussions will follow.)
