Don't have any warped blades but at 1 to 1 1/2 inch its kind of like a thin hone with a lot of maneuverability.

Have made a few paddles. My personal one's are jarrah with roo on top. Have made some only 1 by 12 inch and they work just as well as the 3 inch ones if not a bit better as there is more flexibility...
