Wire measurements
These are the standard wire measurements for a Jiffy reed or blank. I measure 1mm from the top of the first wire to the collar, 9mm between the top of the first wire to the bottom of the second wire, and 4mm between the bottom of the third wire to the butt of the reed. The blade is 27mm, and the tube is 28mm, making each reed 55mm total in length. Below you will find shape and profile dimensions, courtesy of our good friends at Barton Cane.
