Any theories on why Polsilver SIs get smoother with use?

I had my second shave on a Polsilver SI this evening, and sure enough, it was smoother than the first.

If this week goes anything like the previous two, this blade will keep getting smoother with every shave.

Does anyone have any theories on why this happens?

Does this happen with any other blades?

Let's block ads! (Why?)
