Yes big,big diffnerce between handling/forming/shaping woods from green-wet to dry-hard.
This can be observed in many ways.
I tried to explain this once . . . feel that I failed then.
So . . . again . . . maybe. . .
"Wood’ is many separated layers of fibers. Wet and/or sap filled between the layers of fibers and cutting/searing you are mostly only streach, then nick cutting one fiber layer at a time. The dense, non-compressible moisture’s filling between the fiber layers serving to keep the layers somewhat separated for individual layer cutting.
“Dry” woods and the empty sap spaces between the fiber layers are easily compression pressure collapsed. The fibers layers stack up then presenting you with a fiber bundle to have to handle. Out-of-many:One. One tough made problem to handle then.
Rotary toothed sawing, and blade planing of dry wood works so well because these are a lifting actions; Not compressing down on the fibers layers.
