In that case you're right, Rinaldo needs to get off his ass and make another combat cross, or even combat cross 2.0 with Grapple Gun functions.
^- Win. Please make sure to have Quad Plasma bullets.
Now keep in mind this is only speculation and observation as a writer, reader and plot analyst -
At the end of Resurrection, Gabriel only destroys the hilt of the weapon in the dimensional prison. In order to get in to these events, he and Laura used the infernal time machine created by the mad scientist. Now to clean up this mess, one of the posters (who's name I had forgotten) had stated one of two outcomes that are speculation and agreeable.
1.With the use of the time machine Gabriel and Laura go back through time. As they are at the prison, the “future” Gabriel is already fighting the Dark Lady. The reason why I state this is that if you read the scrolls, one of the soldiers of the Brotherhood state that the “Lord of Necromancers” some how tampers with the seal that locked away his blood orb (hence why we have to do the portal puzzle.)
2.The second out to this is that it only restores that portion of the prison (which a poster has stated.)
Now about the Combat Cross itself as I was speaking about before – if you read the description of the upgrade itself it will state the following:
“Rinaldo Gandoffi built
two different chains for the Combat Cross, but one was never approved by the Brotherhood, for other reasons. The elders thought that the spikes were too cruel for the holy measure of the weapon. However, instead of destroying it, the artisian hid the links in one of the old mausoleum of the Order, believing that one day it might be needed.”
This is just half of the quotation taken from the actual game's description. Two chains? Let me get this straight, if I had read this correctly: perhaps there is another “Chain” in which we never got or perhaps it is speaking on behalf of the current chain in which we start with. One thing is for certain, the whip will be reconstructed because the Hilt was only destroyed – we did not in fact see any remains of the chain itself when the weapon was shattered.
Secondly, if my theory is correct with theory 1 stated above, I assume that the “original” chain is locked away in the dimensional prison, in which it may be so that Gandoffi himself or another “Belmont” (if there is one) will reclaim it and the true Vampire Killer will be (re)born. But what puzzles me more is the "second" chain mentioned in the upgrade's description.
that's still a very vague reason why a family can use a whip that was soul-bound by a forefather.
and yet again, where are the drawbacks? trapping a poor woman's soul in a whip forever for the ultimate weapon of destroying evil has to have a catch.
What took place in LoI's forming of the Vampire Killer was the first law of Alchemy, The Act of equal exchange. As the post stated above, the whip needed a tainted soul in order to reach its full potential. Then of course we have the "Trust" foundation between Leon and Sara. Basically in a sense - a soul, for a soul. Life for death, death for life...etc...etc. (:
