I cut and paste this but it sounds feasible.
It is important to know whether your bow saw has special hardened teeth, which is very common in the saws sold today. This can be determined by consulting a representative at a local hardware store. Bow saws with special hardened teeth cannot be sharpened, and attempting the sharpening process on them will damage them and make them potentially unusable.
