For sale is a Sharper Image Dynablade 4000 electric razor. This razor was introduced in 1998, and I believe it was only made for a brief period of time. It takes Sensor cartridges, and Gilette sued Sharper Image's pants off for making a razor that did that. It is a vibrating, electric safety razor. The piece is new/sealed in the plastic, making it a rare collectible. Note that ti does have some marker marks/writing on front. It would be a great addition to any collection!
