E-Smart Handle 3.74" x 1.26"
Series 063 Felo E-SMART Handle, for use with E-SMART blades
The first compact smart tool for electricians.
Secure fit of blades, with quick-release button on handle
I think this is the best interchangeable blade driver I have used. The blades have a nice solid feel when locked in the handle, and the blades come with a thumb spinner that is detachable so they can work without the handle. Really solid tools.
