Where I live, this is what we call a swede saw. Don't see many of these nowadays and they command a good price when available.

This saw is a smaller one and there are some that were easily double the length and width. I remember when I was a strapping and strong teenager and having to pull on one of these saws. It was extremely difficult to maintain a good rhythm and did not take long for the arms and shoulders to start aching...

These saws required a lot of cooperation with your partner and history books have stories of friends and spouses arguing that the other was not doing their fair share of the work. Many times, the arguments were long suffering and vehement enough that they eventually led to enough bitterness to permanently end the relationship.
