Hello, everyone. I took my first steps into straight razor shaving, and got two Weck Sextoblades, one regular (plastic scales) and a Medical Sextoblade (metal scales). Here they are: The Medical looks pretty good on the surface. It pivots fine, tight and well. The regular has a loose pivot pin, at around 90° it can stay in its position, but even a light touch will make it fold back in, or outward. I hope to correct this by doing something like this. But they both have rust inside the blade arm. I thought the metal one was fine since there was no rust on the blade in it, but there appears to be some in the close-up photos. The regular is bad, according to my completely inexperienced judgement. I had to use pliers to pull the blade out, and rust is visible even to my visually impaired, naked eyes. Here's the inside of the regular, as best I can photograph it: And the Medical: What would you experienced people recommend to treat these? Should I try to jam some sand paper in there and go back and forth? Any liquid products they should have a swim in? I've never purchased antiques in my life before, and I don't really have an idea where to start with these. I could just shave along, as the rust isn't on the blades themselves, only inside the blade arm. I'd like to try to care a little more for them though. And does anyone know what kind of metal the regular one is made of? The Medical is stainless steel, I believe, but the regular doesn't have the same silver-ish look. Is it brass? It looks a little dim, wondering if I can polish it or something. Thanks for any help.
