As you may know, Wal-Mart is replacing the entire Personna line they used to stock with products from Wilkinson Sword (aka Schick). There are new Wilkinson Sword double edge blades, disposables, Atra/ Trac II combo carts, and a new cartridge razor called the Wilkinson Sword Tech 3:
The Blades are even made in the USA!!
The Wilkinson Sword Tech 3 cost $5 with two cartridges, and replacement carts are $5 for a 4 pack ($1.25 each), so quite economical.
The pivot style is similar to that on a Sensor, but the attachment point is much wider than that of the Sensor, and even wider than that of a Schick Hydro.
The cartridges will thus only work with the Tech 3 handle.
In the interest of trying out new things, I bought both the razor, and a refill pack. I will take them for a whirl this coming week.
