Riddles

[milo]

I added another couplet to help in solving this riddle.
All six lines are examples of this versatile word/object:
Versatility
It can bathe a daunting monster
or secure a surly mobster,
convey a colossal cargo ship,
yet gather in a pink ribbon strip.
It is lover’s lips in a fit of schmaltz
and also a step for those who waltz.

Sorry, i have been away, i assume it is a 

bow

---

The more they take the bigger that it gets -
I’ve had some problems with my riddling neighbor.
You see, he just can’t seem to mind his pets.
They cross the fence to steal what’s mine and yet
The more they take the bigger that it gets -
Like thieving little convicts at hard labor.
We have a leash law but somehow he “forgets”.
The more they take, the bigger that it gets.
I’ve had some problems with my riddling neighbor.

No, but I see how your guess fits several of those lines. This word has so many meanings and multiple spellings, so that the more clues given, the more confounding it seems. So here's a few more   :

Versatility

It can bathe a daunting monster
or secure a surly mobster,

convey a colossal cargo ship,
yet gather in a pink ribbon strip.

It is lover’s lips in a fit of schmaltz
and also a step for those who waltz.

It can be a hold in the sport of wrestling
or means to keep a wheel from turning.

In the series ‘Lost,’ it was a character’s name
In England, a philosopher of certain fame.

Breweries use one to aid in aeration,
another kind can set a bullet in motion,


(I will work on yours)

well, mine did fit before, every line actually so this newer form is more "correct" imo as it prevents "bow' from being correct.

now I see it is a 

lock/loch

mine is actually a take on an old classic so i dont get full credit.
