I'm considering buying a couple of the harder to find razors, if/when they come up for sale and if I can find for a fair price. I have seen razors that are NOS / unused, but I fear that if I bought any, I wouldn't be able to use them or the value/collectability would drop dramatically (even if I cared for them very well).

What does everyone think about this? Ideally I'd like to be able to shave with and enjoy any razors I buy, and would do so if it only dropped the value slightly... or does using an un-used razor drop the value significantly for the rarer models?

Also, with a NOS razor, is it OK to have it professionally cleaned/polished, or should it be left exactly as-is?

Would appreciate everyones thoughts on this.

Cheers. Andrew
