I'm new around here, so please go easy on me... It seems it's been quite a while (based on a search I did) since anyone brought this up as a question... Is it actually beneficial? Do folks typically acquire two sets of shells just to secure two thrust halves? And what's the point of adding a tang if the thrust sides already ensure it stays in place?...(edit. Oh, I see! It's to prevent rotation... learned that from another source)
