The main reason for dual blade was pretty simple. You have twice as many inches of blade to wear out so you can make a cheap blade and to get the life span up, use 2.
So at three blades of the same quality you see about 50% more lifespan so just on the time between changes you see a gain.

I prefer the dual and triple blade systems since I don't want to spend the 20 minutes with the system James Bond used.
Hey guys, just out of curiosity, anyone use a newer type razor that's more than 2-blades? Are they really worth it or produce the desired results? I've used Trac-II for years and similar ones as well, but overall don't understand why the cost is so high for x-blades. I believe one day, they'll be 10-blade or better models and one swipe will you're done shaving.
