Recently picked up a small Disston saw in pretty tough condition. Based on the emblem, it is from 1896- 1917, so at least 100 years old. With this particular restoration, my goal was to keep the "aged" and "weathered" look as it had a great patina. To start, I disassembled and soaked the blade in vinegar for 24 hours. I next strightened the blade and then sanded with 220 grit followed by 380 grit. The vinegar left some dark spots in the deeper pits of the blade, could probably take them out with a wire wheel but the goal was not to make a brand new saw. With the handle, I first used a soft tooth brush and some light degreaser as it was covered in grime. Next I wiped down good with mineral spirits. At this point, there was some I think lacquer left on the handle along with paint splatters which I opted to leave as-is to keep the patina. I finished with three coats of Tung Oil (24 hours between each coat) and lightly polished the brass hardware. Overall pretty happy with how it came out in being able to preserve the patina of the saw/ handle but still having it be functional. Should be good for another 100 years. Only thing left to do is sharpen the teeth.
