Is it a Fly or a Bee ?
The picture on the springhead only became a bee-shaped decoration in the 50s.
Previously it was always classed as a fly, as the "fly" is a technical term used by knife manufacturers designating the part of the spring that becomes compressed during the forging of the spring itself.
As the bee was considered much nicer than the fly, legend has it that Napoleon allowed the first bee-carvings, but this is just a story.
Old Laguiole knives bear no motifs on the fly, and older knives still have no picture at all on the springhead.
