That is true, Pam. Trying to horse a 4x8 sheet across a TS scares the bejeebies out of me. I break them down with a circ & guide first. Tearout is prevented by making a saw board that both guides the saw and supports one side of the cut. Make a scoring cut first and it's good and clean.
Now I see I will have to get the LV plywood saw:-) How is it on solid wood? I'm guessing it has more set than a normal Japanese saw. As I'm working with SYP lately, that may be a good choice.
By no means take my comments on hand-cutting plywood as the last word. I just know I've tried it and didn't like it.
