Thread: Hayashi Diamond Arrival

Just arrived in the mail! I'm having difficulty finding information on it. Any info when these were manufactured? I'd like to clean it up, but the blade where the etching and stamp seems pretty uniform in color... Is it patina or is this the way it's supposed to be? Info what the scale material is?

If it were me, I’d just hone and go. Patina is great, a sign of a well cared for razor. It is the black. And red rust that we want to get rid of. That beautiful grey is either a gift from nature, or applied. In either event it will actually help protect the steel much like bluing does.

I was polished, is carbon steel and tarnished, possibly WWII vintage. It should easily polish back up with a wine cork some 600 grit Wet & Dry and 1k. From 1k it will easily polish with any good metal polish.

You also may have some luck with just 000 steel wool and metal polish.

They are nice shaving razors, though yours may benefit from a couple layer of electrical tape to make up for hone wear on the spine.
Scales are likely celluloid. or another form of plastic. They too will polish with good metal polish.

I'd work over the heal and put some tape on it and hone it. The color is so uniform. It looks good.

Hayashi is know to use very good steel. Great shavers!
