Tom Lie-Nielsen in his video, Saw III, says this as he encourages his viewers to learn sharpening. With the excellent Vintage Saw treatise and many articles and videos gleaned from magazines and the internet I have been able to repurpose a 16 tpi Veritas crosscut saw as a dovetail saw. This is no big deal to the experienced, but I had difficulty with the small teeth and my bad technique. Now after resetting, jointing, and refiling the teeth, I have a good saw and the pleasure of making it happen. If I had bought a really good saw costing north of $200 I doubt I would have submitted it to my remedial filing, instead returning it to the maker. The packing, the time lost in turn around, the cost, and the dependency would have been irksome.
The question arises whether owners of these high grade saws do the touch ups themselves? I'm guessing they don't as it would be hard to accept a performance loss or the fear of such. Your opinions, experience?
