First off, this post isn't to be read as prescriptive but just thought provoking!!!! I want to show that certain metals have outside benefits that others don't. It's to be informational only!!! I've had dozens and dozens of razors, some vintage and most modern, stainless steel. My newly owned KARVE is the only razor I've owned so far that is made of brass. Other companies offer razors in bronze, too. For a bit of metallurgy background, brass is a combination of copper and zinc and bronze is a combination of copper and tin. My brass KARVE is beginning a beautiful transformation process of tarnishing. I was totally taken by this when I saw it getting darker, like a door knob from an old home. I first wanted to polish it out. I am now not worried by it. Brass razors have character. I'm actually happy to find out that razors made of such alloys have other benefits, too. They are antimicrobial. I somewhat knew this from my chemistry background that certain alloys are, in effect, antimicrobial. This is called the Oligodynamic effect. Brass being one metal alloy that can kill bacteria in a matter of a few hours, as well as any antibacterial soap. Silver is even better at killing bacteria than brass and bronze. Doorknobs are probably the most touched objects in the world. I'm still wondering if brass was chosen in the past to make doorknobs because of its resistance to moisture corrosion or because it can protect the public from disease transmission when using high volume doors? Furthermore, brass is highly used on marine vessels for being antimicrobial and resistant to moisture corrosion. Stainless steel can RUST; never let someone tell you otherwise. Stainless steel is just much more resistant than bare iron (Fe). Brass and bronze are super at being anti-corrosive. They will tarnish but maintain their metallurgical properties at the surface. You've probably noticed from museum visits that many lasting artifacts were made of such alloys and are thousands of years old. When considering a new razor purchase, consider brass and a couple of other metals for having the ability to clean themselves from germs. In a given amount of time these metals are able to sterilize themselves! Stainless steel and aluminium metals aren’t able to do this. Most people clean their razors very efficiently and shouldn't be alarmed by this discussion. It's always good to disinfect ALL razors when buying or passing razors around. Brass and bronze just might have your back better without knowing it. LoL. The tarnish look can also be very attractive. This is not an advertisement for brass but just an educational argument for not being afraid to try another metal, other than the usual SS that we might all be accustomed to. SHAVE ON!!!
