I have a cabinet to make with a couple of drawers. I'm considering
hand cutting dovetails for the drawers and for top rails of the
carcase. When I have cut dovetails previously I have used a tenon saw
or a "Junior" hacksaw with reasonable results, but I'm wondering if it
would be worthwhile buying a specialist dovetail saw. There appear to
be various types and makes available on the web including pull saws.
Any advice or recommendations?

I only cut dovetails once in a blue moon so I don't want to spend a
lot of money on a machine jig. I also get more pleasure from "hand"
woodwork than "machine" woodwork.

TIA
Pete
