Yes - I have a boxed pair of Wilkinson Pall Mall straight razors, very cool, was surprised when they showed up and they were 4/8th.

As WadeP mentioned, they turned out to be, and still are, superb blades...and that's one of the many aspects of the fun of this.

We're probably some of the few people on this planet who could tell someone, in complete seriousness, dozen's and dozen's of different ways to shave, with each being enjoyable and unique!
