Just won a bid on a razor off ebay. Gillette with 2 bands. Put a Merkur blade in it and it stuck out the sides by about an 1/8th of an inch on each end... ? Do I need to put special blades in it? Thanks.
Do you mean the blade's cutting edge stuck out, or the sides of the blade stuck out. Most blades tend to have some overhang on the sides, they kind of look like handles or something. If the cutting blade itself is sticking out then that is a whole other matter.
That's normal, even with modern DEs. This way you can exchange blades much more easily because you can grab it at the sides.
