I don't think "6IV" has any confirmed definition (I'm guessing this is why the forum rules say you should explicitly state the IVs of the Pokémon in threads).
Personally, I'm not a fan of
any random IVs on a Pokémon. 0 Attack lowers confusion and Foul Play damage. 0 Special Attack lowers Power Split boosts for opponents. 31's and 30's (and 1's sometimes) are required for specific Hidden Powers.
So 31/31/31/31/31/00 is
perfect [ideal] (by my rather abstract definition) for a Honedge, so long as it runs both Special and Physical attacks, and doesn't require a specific Hidden Power (other than Ice).
Even 29's and the like can be ideal for Life Orb / Stealth Rock damage lowering, as well as Substitutes and Berry activations. I seem to recall 07/00/30/31/31/31 being ideal for Leech Seed Sceptile.
