Open the CIPO recordAbstract From the Canadian patent
A screwdriver with multiple bits is disclosed. The bits do not need to be removed in order to be selected and used. The bits are stored within storage apertures in the handle of the screwdriver, and one bit at a time can be selected and moved through a channel from its bit storage aperture down to the drive end of the screwdriver where it can be locked in position for use. The unitary construction of the unit should lead to less loss of screwdriver tips or bits.

Why it's free to use
- Filed February 16, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 16, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 16, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
