The blades and shafts are made from a 3/4" board, with another strip laminated to the shaft. I did this to make the shafts thicker than 3/4". The shafts finish out 1.25" thick X 1" wide. Without the added strip they would be 3/4" thick X 1" wide.
The third and sixth ones from the left are pine with a cedar strip. The others are cedar blades and shafts with pine strips.
I don't have a better picture of the one you asked about, but this one shows the strips better.
The strips are different lengths, but I was not trying to build a matching pair, just experimenting.
