This dare is about the sounds of 'friction'. Friction happens whenever two objects rub together, in most cases, this produces sound.
When I was thinking about this dare, I decided I would have to split it into various parts because there is so much sound variation and possibilities.

This is part 2 of a series, check out part one which gives an introduction to the idea:
https://freesound.org/forum/dare-the-community/45024/

For the first dare of the series we explored sounds produced by friction on woven materials (cloth and related).
Generally these sounds will be very "dry" in the sense that there woven materials do not typically resonate. - There are some exceptions.

So now, we go to the extreme opposite and look for sounds of friction on metal objects.
Generally speaking, metal objects will be the ones that will generate the biggest amount of and the longest lasting resonance. In most cases this will result in the appearance of 'tones' in the sound (the resonant frequencies of the object), although these won't always sound harmonious and pleasant as the resonant frequencies of complex shape objects will usually include plenty of non-harmonic frequencies.

RULES:
- We are looking for unprocessed (i.e., natural) recordings. Processing is not allowed.
- Record sounds created by friction between 2 objects where at least one of the objects is metallic.
- Please tag your uploads with "Dare2025-09" and "friction"
- In the description include as much detail as possible about the material (e.g., "metal bowl") and what objects you used to rub against it (e.g. "fingers", "polished stone", "rough stone", "coin" . Remember that the type of surface is important so you may want to describe surfaces (consider words such as soft, hard, polished, dry, wet, rugged, grooved, etc).
- Consider describing where you rubbed the object (e.g. outside, inside, rim)
- You may want to do more than one take with the same object in the same recording, and variate a parameter. Explain this in the description, for example "rubbing a round polished stone on the bowl rim, then the inside and then the outside of the bowl."
- ANYTHING NOT SPECIFICALLY FORBIDDEN BY THE RULES IS ALLOWED.
- ANYTHING NOT SPECIFICALLY REQUIRED BY THE RULES IS NOT MANDATORY.

Noticeably rubbing a Bass guitar string with paper or essentially a screwdriver.
Also using a nail-file of a keychain knife.

LOL - it did not occurr to me that people would record instruments.

Two other sounds.
Beyblades-X's metal blades rubbing against plastic/cardboard.

Friction is a weird thing, does this qualify as friction or lots of small clashes ?

Here's some ideas for metal friction sounds :
-Id love to hear a diamond tip tool scraping against a big metal garage door or something big.
-There's probably room to play with heavily rusted objects, the un-even surface rust brings would probably bring out more friction sounds than most smooth metal surfaces we find.
-Chainmail probably has a "woven" texture to it which would make an interesting sound.
-Id be interested in some sort of anglegrinder or sand-belt or dremel or anything that can produce a constant "droneing" rubbing, against a metal sheet being heated up by a blowtorch, hearing maybe a pitch or ringing changing?
-Crowbar being dragged on pavement
-Tibetan singing bowls is a thing that comes to mind, I don't have one but it's probably an easy "rubbing metal" sound that's harmonic
-Id definitely try a cymbal or gong, I wonder if rubbing one with a bow or other would produce sounds? If not, id try a untied bass-string (with the spirals texture) and rub it along.

Cheers!

Hello Sadiquecat

These are absolutely amasing sounds!
They sound more 'plastic" than metal. If the metallic object is not free to resonate (or does not have resonance) then will not produce a typical metal resonance.
That is OK, as it meets the rules and is actually giving us more sonic variety to work with

You can hear a constant sound from the Beyblades-X spinning (that is definitely friction).
About the "small clashes" it is a matter of scale (in time and in size):
- Think of the teeth in a saw a saw with large teeth moving slowly will create a series of "bump" sounds. If you move faster, they become almost a continuous sound.
- It is easier to produce a smoother sound with a saw with small teeth (each 'bump' sound is smaller and they come closer together)
- if instead of a saw you have a file, the teeth are very small and very close together. Plus, there are several teeth side by side, so many teeth rub against the target material at the same time or nearly the same time, producing a much smoother continuous sound.

So as you reduce scale in terms of time or size, you go from individual "bumps"/"clashes" to continuous friction sound.

Here's an extra sound, perhaps more in what's expected from the dare

To reply to your post. The container the bayblade is in is plastic, but the blade/outer thing is metal, I took the roundest blade I had so it could be mostly friction without bouncing too much, not perfectly round though (that would be OP aerodynamics! / Stamina)

Cheers!

yes, this is closer to what I imagined the typical entry would be.
