Random questions about the MMC

What finishes were MMCs released in?

I know the latest were pyramatte but confused on if earlier runs were bead blasted or soda blasted or both and if both which runs were which!

Also has anyone compared al markmont side effects with the al JTs? Are they actually the same weight or is that a mistype on the website?

I have a couple, one is bead blasted and the other is soda I think (coarser blast), not sure which runs were which though

Soda blast is smoother or coarser? I thought it was smoother because people say they’ve worn off their soda blast etc

If it says they’re the same weight then they probably are. I think JTs are a little flatter than MMs but they have the hole filled in. MMs are rarer than the yoyo though, because they only came with some early runs and basically don’t get made anymore.

Soda blast gets worn off if the yoyo isn’t anodized, I believe. I think this is something you can hear in the summit doc.

Pretty sure you would soda/bead blast in addition to the anodisation, but the rough surface will make it more prone to being worn down than a smooth finish like Pyramatte™.

The soda blasted yoyos I’ve used all have a much finer and smoother blast. My friend with a soda blasted MC intentionally chooses to play a second pyramatte MC instead so they don’t wear down the blast.

I like soda blasts and really fine blasts, but it does kinda suck when you play them enough to the point where they start to feel sticky and look glossy. When you intentionally bought a yoyo and wanted the blast, it kinda sucks once it’s gone and makes you feel like you need to either find another or just blast the yoyo again yourself.

I actually didn’t know OD did bead blasts at all, so I can’t speak to what those are like.

Yes! I was under the impression that the mmc had the same blast that the overture used(which was a super fine silky finish).
But I got it and its rougher than the overture so maybe it was a bead blast not sure. Would love to try a soda blasted mmc to compare​:sweat_smile:

I do want to push back on this idea that a finish can be worn down smooth on an anodized yoyo. Its applied on the bare metal and then anodized which is a much harder material. How can just your hands and some air drag wear it down. Maybe hand oils gum it up but wouldnt a good clean freshen it up!?

In the same vein I also think the whole rub denim or leather in the response is suspect, ive never had it work in wearing it down​:sob:

What is there to push back against? This is really normal for people who play single yoyos a lot. And it’s not exclusive to blasts or anything. Just wearing down through the ano. You’ll see anodized glossy yoyos worn down to raw AL in the same way. It’s honestly even more pronounced in real life. You really feel the difference from what the blast started as in the cup compared to how sticky and glossy the profile has become.

The most well loved single yoyo I’ve seen is definitely this example. Fixed Axle Friday Throws - #3407 by Xanadu

This page, cited by Wikipedia’s page on “stropping”, describes how even clean cloth/leather (i.e. no abrasive agent applied) can alter steel: What does stropping do? – scienceofsharp. Stropping is used to maintain the edges on hardened steel blades, but I think the same principles apply (especially micro-abrasion and burnishing). Anodized metal is hard, but the changes are occurring at a microscopic level.

Apart from that, hands oils are bound to include some level of acids and grit.

Im not pushing back on the fact that it happens, that rbc is a very strong example!

I was just confused on how can it even happen since I always thought you needed the compound on a leather strop for it to be actually effective.

But it seems from the link @hsb shared that a leather strop can just realign the material. So what might actually be happening is that the ano itself doesnt wear down but the blast tamps down or something!

Still going strong but yes I have worn through most of the navy finish and there is a pink undercoat underneath. The RBC is 7068 aluminum alloy, which is the hardest/strongest alloy that is available. Some of the wear is from finger nails (in the dimple) but most of it from having it in my pocket.
