"Singing" Razors

So, what makes them "sing"? I have two razors that just ring away on the strop. One is a Fili #14 re-brand; the other a big TI. The sound is subtle but unmistakable from the TI. The #14 practically shouts.

There does appear to be some variation in each razor's song as they go back and forth, but it's not clear to me what is causing this: speed, pressure, angle, edge, other. Any idea?

What other razors are known to sing? Do I correctly assume only hollows will sing?

The thinner the grind the more singing.

I have found the Fili 14's sing the loudest, they are amongst the most hollow/big blades i have seen

My Dorko #856 sings loudly when I strop it. I would imagine it has something to do with hitting the resonant frequency of the blade that makes it sing? Just a wild guess....

Gold Dollars must have forgotten the tune, as they generally just hum along...

They sure do!

This 15/16 Wacker can be heard singing fifty feet away.

Japanese "Elephant" razor. It was made on another planet. Possibly one without liquid water, as it will oxidise if you look at it too long. It is redonkulously thin as well. A strange creature.

I wish I liked those paper thin blades. I may need to try one again.

My Heinrich Klein. You can tune a violine when stropping this blade.

Great shot. Love how the hand holding the razor is out of focus like that. Maybe my monitor's off, but the flesh tone seems a bit purplish-magenta from my end.

Haven't heard a singing razor in a while. I think I've just become used to them.

This is the fili re-brand mentioned below.

We need better pics of that elephant razor and kamisori that show the whole razor, i'm really curious!
