If the razor was sold to you as new, here is a really easy way to tell.

Was the box sealed as it may have been originally from the factory?

If so, it's not shave ready. It may have a "factory shave ready" edge on it, but that will never be as good as an edge honed by a professional.

Also, a "look-over" can't determine shave readiness. If that's all he did, it's probably not shave ready.

You're on the right track sending it to Lynn. What you receive back will certainly be shave ready. It may even be shave enthusiastic!
