This is an awesome Canadian-made precision bow chainsaw produced in 1946-48. This Montreal-made precision bow chainsaw of high quality is greatly different from the current bow chainsaw models used in today's works.

This ancient beast is equipped with a scratcher chain, a kind of design that involves a series of teeth that in principle scratch the surface of a wood.

Unlike the old chainsaws, the currently used ones are designed with chipper chains which are produced with several features to adjust the depth of the cut.
