From that chart:

Best Weapons by Level:
/.../
Level 62 warder: 2 H2H weapons only. Minimum weapon damage to be useful is
36.
Level 64 warder: 2 H2H weapons only. Minimum weapon damage to be useful is
37.

Err, H2H weapons with dmg > 36.
Do they exist?

The chart does not mention procs. Any weapon with a proc will be used
by your pet. So the mage summoned ones with the DD on them will add to
his combat abilities. I like giving my pet a couple of gnoll hide
lariots. They proc a stun, it's nice to see my pet chain stun caster
mobs. (Of course I'm a shamman, so it's not quite the same thing, my
doggie will not dual wield unless I give him two weapons.)

When I want the toughest pet possible I summon foci for the pet -
they add 160hp and more AC (2 bracers, 2 rings, 2 earrings, neck,
shoulders.)  I also summon an elemental defender -- give your pet
weapons first then the shield and he'll equip it on the back slot,
otherwise he'll equip it in the offhand and stop dual-wielding.

Yes, and that's the most succinct way I have seen it put  :)

Palindrome

3 words:

Glowing. Black. Sword.

Actually, if the pet's base damage is less than 2x the weapon
damage then a weapon will boost their damage.  However, for
PoP pets that would requie a 45 damage and up weapon.

Pets at least used to be able to equip items that were NONE/NONE, so, they
could use things a warrior could not.

It will not effect delay, but if the weapon is sufficiently powerfull
it will up the damage. It's just that most pets (at the level people
can afford to buy summoned equipment for their pet) already do a very
nasty amount of damage, and it takes a very strong weapon to increase
that. (The kind that no one wants to give to a pet because they sell
for thousands in the bazaar.)

He shouldn't do any more damage with the things; their damage rating is
10, which means any pet which does more than 20 points as his max hit
isn't going to do any more with these weapons.

Damage by a pet is best of his own damage or 2x weapon damage.

For most classes, a weapon with damage of 10 is useless for increasing
damage by the time they are level 16 or so, I'm not sure of the
specifics for a beastlord pet.

Delay of a pet is unaffected by weapon (unless its a haste weapon, which
is unlikely)

There is in some classes a period where the pet will dual weild if you
give it two one handers, but not without; during this period giving pet
any two weapons will increase damage output overall by increasing the
number of swings taken... two rusty daggers will do that job as well as
two 50/50 one handers if you could find such things.  Most pets, this
period lasts a dozen levels or so and then they dual weild without
needing the hint; shaman pets are one exception to this, they -always-
benefit from a pair of broken bottles or what have you.  I'm guessing
Beastlords are not an exception.

How, then, do summoned weapons increase damage output from your pet at
high levels?  What he -is- supposed to do is proc with them, thus doing
extra damage that way.  They also boost his HP, so he lives longer...

Then you also get him a haste mask (muzzle of Mardu) which will make him
swing more often... still not for more damage, just more often

And you can round that out with a HP belt which includes dex to make him
proc more often (both the weapon procs and his own beastlord buff
procs), plus armor to increase his damage mitigation by raising his AC;
mages can summon plate armor for every "visible" spot on your body,
which is fun for handing out to newbie paladins (its red) but useful for
AC buffing pets.

Usually each of the above is available for 5pp or so in the bazaar any
time day or night, exception being the armor, which would be
inconvenient to sell like that, so is generally only available directly
from a mage in POK, where you can probably also find the rest of the kit.

Is it necessary?  No.  Does it help?  Yep, it seems a full kit is good
for about a 15% boost in your pet's usefulness (combining added damage,
added Hp, added procs, added mitigation); much more if it doesn't
naturally dual weild, astonishingly more if you are under level 20.
