Nazir 54b - Cherev K'chalal

The gemara on 53b learns from a pasuk the concept of "cherev k'chalal" which means that a metal kli that comes into contact with a meis becomes like the meis itself. We find 4 opinions regarding this din:
1. Rabbeinu Tam considers the cherev to be exactly like a meis. Therefore, a nazir who comes into contact with a cherev that was in an ohel ha'meis becomes a nazir tamei. Since kohanim are not allowed in contact with any tu'mah that causes a nazir to be migaleiach, a kohein is not allowed into an ohel where there is a metal object that came into contact with a meis. It would also follow that the cherev would be metamei a person through o'hel, and would be metamei the person for 7 days and he would require being sprinkled from para aduma on day 3 and 7 to become tahor.
2. Rabbeinu Chaim Kohein asks Rabbeinu Tam "what house would you build for me?", meaning that based on your premise a kohein should not be allowed into any house that has a metal nail in it since some metal in the house most likely came into contact with the meis. Therefore Rabbeinu Chaim Kohein holds that cherev k'chalal does not make a nazir be migaleiach, and therefore a kohein is not muzhar against it. However, Tosafos implies that even according to the is opinion, the cherev would still be metamei b'ohel and the person who became tamei through it would recquire sprinkling day 3 and 7.
3. Ba'al Hameor in chulin (mentioned in gilyon hashas) and Ramban in parshas chukas hold that the cherev does not make a person tamei through o'hel [which would answer the question of how a kohein can walk into a house with tamei metal, even if we assume like Rabbeinu Tam that a nazir is migaleiach for cherev k'chalal], only through direct contact or carrying. Furthermore, the person who became tamei from the cherev does not need any sprinkling from the parah aduma.
4. Rabbeinu Yitzchok Misimpunt (brought in Tosafos) claims that all keilim even non metal keilim are subject to cherev k'chalal, but Tosafos strongly rejects this approach.
