The tool is an instrument including a filament which is brought into contact with an individual to test sensory perception of the individual. When the filament resiliently buckles a standard force is applied to the individual. The filament is retractable within a housing. The filament is mounted upon a shuttle which moves relative to the housing to position the filament either in a stored position within an interior chamber of the housing or in a deployed position outside of the housing. The filament both translates and rotates to move from the stored position to the deployed position. The instrument is configured to securely hold the filament in both the stored position, where the filament is kept safe when not in use, and a deployed position, where the filament is held firm during use of the filament for sensory perception testing.
