These sculling oars have a compound curved blade, much like a real spoon with hardwood edges and a hollow core tapered D-shaft.

Fly fishing pram oars are designed with a oversized spoonbill blades with a mild spoon effect. The larger blade gives more power as these boats are occasionally used in current and aren't normally rowed for long distances.
