There was a useful sawback, once upon a time: swiss sappers bayonet. It had an 18 inch blade and a steel scabbard, and was perched in a place of honor above the knife display in the village army-navy store in 1962. I had saved up the money to buy a mercator folder, and did so but was smitten with the mirror-polished stainless steel blade, double row of offset saw teeth, and elegant wooden grips. The mercator was 2 bucks; the swiss gem was priced at a princely $12.50-In comparioson, mundane M-1 carbine and garand bayonets were available at $5 each, complete with a broken tipped scabbard. When I finally acquired it, I discovered that it would indeed cut wood, but found it burdensome for EDC.
