The Stainless Steel razor is exactly that - a stainless steel blade set in stainless steel scales (only the rust-resistant washers aren't stainless) - which makes it suitable for use in an autoclave. The 5/8" blade is full hollow ground with laser etched branding. It also comes in a metal case to keep it safe between shaves.
We will hone and strop this razor before we send it to you at no extra charge, so that it arrives truly shave ready. The general consensus among those who shave with cut-throat razors is they are not truly shave-ready straight from the factory (even though the manufacturers often claim that they are), so having your razor honed before use is important.
