Riddles

Rifles? Tenchr

[Gojira]

An artifact?

[StrandedonEarth]

I know this is late but I must protest that, as Red Iron Crown noted, CCl₄ is by definition not a CFC (chlorofluorocarbon) although, like a CFC, it is an ODS (ozone-destroying-substance). Since that riddle is now ancient history, I will now quietly wander away and shan't insist on my turn to post a riddle, as I don't have one ready anyways. As for the Mechanic's riddle, I have no idea, at least nothing that fits the riddle, only watch-related things.

Sundial? Stonehenge? I doubt either of them

[vexx32]

Crystals? Quartz? Gems? Metals?

[cantab]

Suddenly get an idea while I'm snoozing in the morning: is it a Swiss Army Knife?

Suddenly get an idea while I'm snoozing in the morning: is it a Swiss Army Knife?

Exactly. You're right. Your turn.

From the one between the mountains, -> Switzerland.

more than one there are. -> Variations with different "configurations".

They are many within one, -> Multi-tool.

to be used in the field,

to be found in a museum. -> Museum of Modern Art and probably also museums displaying historic ones.

Four lines I could have added as hints:

History and tradition it has,

modern it can be.

Iconic it is in the colour red,

though others there are as well.

OK, here goes.

Speeding I am harmless,

Miles in which to move,

But slow me and confine me,

And I will level all.

Fixed typo

[Red Iron Crown]

An explosion?

Second line is meant to say "miles", yes? Not males, moles or mules?

[cantab]

Whoops. Yes it was meant to be miles, and no it's not an explosion.

[SiliconPyro]

OK, here goes.

Speeding I am harmless,

The bus from speed?

[toolofdarkness]

it sounds like a wmd to me or and atomic reaction. is this close?

[cantab]

No, no, and no clues yet

[The Mechanic]

An asteroid?

[Starwhip]

Water or light. Probably not light.

Or water. Hmm.

Asteroid makes sense, but I'm a wee bit late.

[cantab]

Water is...relevant, but not the answer.

[Sun]

The moon?

10chars

[The Mechanic]

Maybe rain? Waves? Hm. Sounds more like a river than the former two?

[cantab]

No to any of those.

Speeding I am harmless,

Miles in which to move,

But slow me and confine me,

And I will level all.

Water is relevant.

[The Mechanic]

How about steam?

[cantab]

Nu-uh 10char.

[Sun]

Clouds?

10chars

[The Mechanic]

Could it be the tides? Or ocean/the sea in general?

[Xorth Tanovar]

Tsunami

...

[cantab]

Tsunami

...

We have a winner!

Speeding I am harmless, - in the deep ocean tsunamis move very fast but are practically unnoticeable

Miles in which to move, - specifically, miles vertically; in a tsunami the entire water column from surface to seabed is in motion

But slow me and confine me, - As tsunamis approach shallow water they slow down

And I will level all. - pretty self-explanatory

A short one, then:

What belongs to you but others use it more than you do?
