I’ve been looking them over on Craigslist but didn’t buy one yet. I bought new blades for bow saws that are easy to transport if you’re on foot. All the old two man saws need sharpening and conditioning. I’m fortunate to have a saw set for large blades I bought with a bunch of other old tools. I got it 30 years sgo just because I like and use old tools. It should only take about an hour to fully recondition an old saw.
As I think about using hand saws, a sturdy sawbuck will be extremely useful. A buck holds the wood still and at the proper height. Ergonomics becomes very important when using manual labour all day, every day. Good egros will save loads of energy and save body parts. Two man saws should be used up high, above the waist.
