I used a Shick Extreme disposable razor for about 30 years. Came in a 10 or 12 pack, costing about 50 cents per razor. Sharp blades, close shaves and lasted one week like clockwork, before I pitched them out.
Then one day I brought home a new pack, and the razors had dull blades and a useless pivoting head that serves no purpose. I looked online and apparently I was not the only one who had this experience. Some genius at Schick decided to replace a perfectly good razor with a totally crappy product.
Fortunately, I found something called the Schick Exacta on Amazon. Apparently it's sold mainly in Latin America. Ordered a pack and they were pretty close to my old favorite. Slightly differenet appearance, but fixed head with sharp blades that last about a week. Went back online and ordered about a two-year supply, in case they too disappear. I feel like one of those hoarders who stores canned goods in a Tuff Shed, preparing for the end of the World.
