Oh boy do they! I shaved with DE's for over 50 years until I discovered the forums and the joy of shaving with a straight. I must have had 25 to 30 different DE's from some of the earliest to the most modern, and each one seemed to give their best shaves with only one or two particular blades. The best thing to do is to buy a sample pack of a dozen or so different blades, and try them out in each of your razors. Of course there are many other things that contribute to a good shave with a DE, such as blade gap. Within a year of discovering straights, I sold all of my DE's except a Gillette slim that I purchase new in 1962 and had thousands of good shaves with it.
