The Rodio-craft CHA2
At just 1/2" long and 1/3" wide, it is the smallest spoon I have found. Still, at .9g it is almost twice as heavy as the Blinde Flanker .5g spoon. With a UL or XUL rod and a 2lb or 2.5lb line, they should cast very nicely indeed.
The CHA2 jr. spoons come with a single barbless light wire hook that is extremely sharp.
Length 1/2", width 1/3"
