I used Trac II blades for many years. They were expensive and I was poor so I would try to make them last at least a week. What torture. I then played around with electric shavers, some cheap, some expensive. I was never happy. Then... Eureka! I discovered DE and use a fresh blade every time I shave. Now I use the most expensive blades I can find (Feathers 30 cents a piece). I truly delight in throwing them away after only one use. The torture has ended along with $3.20 MACH 9's.
