Every design works on paper, 

Design 4 , worked ok but not good enough to sell. 

Cool concept, didnt work at all, scrap-yard lullaby. 

Teamwork  2009

Coffee break at the McDonalds 2003

Design 9, Its all there, floating wings, floating box, trip edge, Lexan moldboard,  More minor design changes for Design 10 include increasing the height of the wing tips, making the wings pivot up and further back so they wont accidently fall when backdragging and strengthening the wing mounts. I still use this blade. 

Design 7, The Lexan moldboard floating box,  and trip edge are perfected  but no floating wings yet. Notice how wore down the polly shoes are. Not great.
