I have seen a few times on ebay what is called in French a Butterfly Straight Razor (coupe choux papillon). Basically, these are straight razors with two blades in a single unit of symmetrical scales. My attempts to find information on these razors ended up without any results (probably also because I don’t know what they are called in English, and because TTO DE razors in French are also called “rasoir papillon”.
Does anyone here have any info on these, and what they are designed for? This is what they look like.
Never saw one if those before. My comment is purely based on observations.
Maybe you can sharpen the blades at the same time. One with the down stroke on the sharpening leather the other one with the up stroke. The sharpening uses the same time but you can use a sharp blade twice as long.
