Note: I've just emailed my rav to request a psak, this question is purely to explore the halachic background of the issue.
Does second-hand silverware require both tevilah and kashering? If one is living outside of Israel, one might easily expect that the original owner was not Jewish, necessitating tevilah. However, this brings the crux of the matter into light. Does
- Tevilah pre-empt the requirement to kasher pre-used flatware?
- Tevilah have the same priority as kashering?
- Kashering pre-empt tevilah?
