Calamo Dagger

The idea for the design of this knife was to make a very tiny knife which when closed would look like a fountain pen. At first, this was a big challenge due the very small amount of space available to fix the movements, the bearings, and the lock, but after a number of prototypes, Antonio Fogarizzu found the way. The blade is fixed on custom ball bearings creating a very smooth movement. The blade locks and unlocks by pushing the curved gold button on the handle.
