The RodioCraft .5g Blinde Flanker spoons are slightly smaller than the now-discontinued Daiwa .4g Vega spoons. The Blinde Flankers are just over 3/4" long by just over 1/4" wide.
At .5g, they will not be too heavy to fish with tenkara rods.
Being both heavier and smaller than the Vega spoons, the Blinde Flanker spoons should fish a bit deeper than the Vega spoons, which will be an improvement, particularly in streams.
The Blinde Flankers come with a single barbless hook.
