RE: Looking for lite ply or doorskins
My dad is a retired floor layer ("linoleum" as it used to be known)
and he usually used 1/4" luan ply for underlayment. He never ever used a saw, always cut everything
with a hawk-bill linoleum knife (Dexter/Russel, all the rest were "crap"!). He kept it sharp with a good single-cut
file.
Anyway, I now cut most stuff like this with an old lino knife as well, rarely saw the stuff. Yeah, it can be splintery!
