Ok I manage to have a little time 

 so I drew up the fades on the side of the blade 1/8 inch to mark where they will be thinned out and redrew the center line and after measured a 1/4 inch on each side of the center line and drew some parallel lines.  That's where the thining starts then tawords the side lines on the blades you don't want to shave in-between the parallel lines this acts like a spine . Hopefully this weekend il take the wood off to show y'all the finished blade edges 


Im prolly going to leave a little more wood here where he nail holes are to make sure it don't break 

Remember if you build a paddle make it your own costomize it  to you if you want thicker blades do it  these are tools and were made to break after being used that's why I chose this burned board if it breaks ohh well il make another
