I can appreciate the desire to keep a fine saw operating at the peak of it's potential performance.I'm a bit surprised that anybody capable of sharpening a saw doesn't recognise that he is already operating on a level way above most hobby woodworkers.I would offer encouragement to visit a car boot sale or two and buy a beat up,blunt tenon saw or two.Take them home and give them a good overhaul,not necessarily to new condition,just to get a good usable saw.Use it,re-sharpen and see how long it takes to elevate your skill level to the point where dealing with a really nice saw isn't such a big mental leap.
I would be exaggerating if I claimed to be an expert sharpener of saws and I regret that my sight isn't as good as it once was,but I do improve a blunt saw every time I pick up a saw file.Which is really helpful if I run into something that takes the edge off as I am trying to reach a significant stage in a project on a Sunday afternoon.By following the advice I am dishing out I now have several saws and tend to select a sharp one while leaving the blunt examples to one side until they leave me with no choice other than having a major sharpening extravaganza.During the course of which I start with the biggest and coarsest saw and work my way down to the more delicate specimens.It seems harder now than formerly to find a really fine saw file and they seem to have bigger corner radii these days but with the aid of an off the stand set of more powerful glasses than I normally use I will keep at it.Any recommendations for a source of really fine files would be appreciated.
