A non-comprehendable "one"

There's one for sure,
who, carves out an isle
from Kolkata, perhaps,
with some useless reasoning.
Though not fully indulged,
in investigation, accidentally,
did I notice one, whom I've been
long waiting for, Who is metres
from me. Not very far from my fully
stretched hand's possible reach out,
is She! She?
He perhaps. He?
'HES', is considered, on an average,
though not authorised.

With sharp broken gobblets in 'hes' hand,
And with a grin outlook, is set for a cut,
which shows the absence of even the slightest
of 'hes' impeccable mannerism.
These, sharp gobblets, being invisible to
our eyes, 'hes' would give a fake smile,
when met. What does 'hes' cut?
'Kilns' of the cause, might be an anagram.
Huh! That's what 'hes' does.

Gone are all those days, when HES'd give
a benovolent smile, which none expected would
turn malevolent. 'Hes' might be one in number, perhaps
Doesn't seem to alter the 'childhood'ity perhaps,
which 'hes' has carried it with 'hes' breath for
all revolutions around the 'sun'.
A non-comprehendable "one",
Perhaps to you too.
