By definition, I do not think you can own the Holy Grail, even if it's a club. After you have found such, it would not be deemed that; again, by definition.
But😄, I do have 2 clubs that I've had in the bag since brand new. Diablo Octane Tour 3wd, and Ping G5i Anser putter. If I am ever asked to go play for $1M, these will be the 1st 2 clubs I put in my bag. Yes, many of each type have come/gone through the years, and may well have worked great/been longer/hit straighter, but not day in/day out consistent. The putter is needing it's 3rd regrip, the 3wd has had many changes, inc. shafts along the way.
