My goal in designing the Razor Caddis was to create an ultra-buoyant fly that could be skated or twitched when fish are chasing fluttering adult Caddis. Instead of dubbing the body I wrapped a thin strip of Razor Foam, replacing a material that would soak up water with one that would repel it instead. I then added a synthetic underwing with a bit of flash, and then a hollow deer hair wing over the top to form a simple, durable, and unsinkable fly. - Aaron Freed
