So we have razor X and it gives me the best shave in the world. There is no doubt it is "shave ready". So I sell it to Mr Smith and he says the razor won't shave worth a darn and it's no where near shave ready.

So what about this concept of shave ready? Is shave ready an absolute objective term? If a razor is truly shave ready should it be for any competent straight user no matter he has peachfuzz for a beard or a beard like a wire brush?

Maybe shave ready can only be a subjective term valid to the current user of the razor only. So a razor can go from shave ready to not shave ready in an instant.

Also what about the term provisionally shave ready? What does that mean? Is there such a thing? Maybe all razors that are shave ready should be called provisionally shave ready.

Put your thinking caps on.
