Henckels razors ?

I'm new to all this, and trying to make sense of what's available.

I've noticed that there are lots of Henckels razors on the second-hand market, and they're not very expensive.

Is that because:

. . . (a) they're not good razors, or

. . . (b) there were a lot of them produced, and they
. . . have no "rarity value" ?

Thanks --

They are very good razors, They were one of the major manufactures so there are quite a few out there
