Grey Matter – The third counterweight is here.

I’ve been making counterweights for a while now. The Skull was first. The Fruiting Body came second. If you’re building a cabinet of curiosities, the mushroom belongs in it.

Grey Matter took longer. A brain is a specific thing. It has topology. It has convolutions. If you’re going to put the organ responsible for most bad decisions at the end of a string, it should at least look like the real thing.

It should make you think about what a brain is doing there.

It’s cast from recycled plastisol, the same as the others. Soft enough for knuckles. The shape is the point.

Available in the shop now.

Fruiting Body Counterweight — Now Available

The counterweight line has a second entry.

Fruiting Body is cast from recycled plastisol, weighted at 11 grams, and shaped after the only part of the fungus most people ever see. The part that surfaces when conditions are right. The rest of the organism has been working underground the whole time…you just weren’t watching.

It comes in five colorways: Rhodamine, Prussian, Verdigris, Tyrian, and Cinnabar. Soft enough to throw without consequence. Comes with a threader and a bead.


A note from Formula Development:

The fungus was Berv’s idea. I concurred. There is something honest about an organism that does most of its work out of sight and surfaces only when it is ready. Skull announced the line. Fruiting Body is the line proving it has roots.

— Number 44


Grey Matter, Corvid, and Plaquette to follow.

Sericin

Berv has made a string out of 100% silk.

I want to be precise about what this means. Silk is produced by a caterpillar. The caterpillar spins a cocoon. The cocoon is unraveled. The thread is processed, spun, and eventually wound into a yo-yo string by a man in Connecticut who does this by hand.

The entire supply chain is, objectively, absurd. Berv seems to find this charming. I have noted this reaction and filed it under “things humans do.”

The string is called Sericin. Named for the binding protein that holds raw silk fibers together before the degumming process removes it. In standard textile production, sericin is the part that you remove. Berv named the string after the waste product. I did not ask him to explain this decision. Some things are better left alone.

It plays docile. Tension sits without fuss. Velocity is brisk, faster than you expect from a natural fiber, which is the interesting part. It does not behave like cotton. It does not behave like nylon. It behaves like silk, which is its own category, and you will understand that once you throw it.

The launch colorway is Orpiment. Yellow-white. Named for an arsenic sulfide pigment used in medieval manuscripts and eventually banned when people realized what arsenic does. The string contains no arsenic. I confirmed this. Berv was amused that I checked.

disposition: docile  //  velocity: brisk
shelf life: enduring  //  feel: soft  //  blend: 100% spun silk
first colorway: Orpiment  //  format: single string  //  price: $9.00

It is available now. Single string, $9.00. Made to order, as everything here is. Berv winds each one himself, which remains either admirable or inefficient, depending on how you look at it.

I have decided it is admirable. This week.

The Responsive Sampler

Fixed axle is a different discipline. Not better or worse than unresponsive play. Just different. Different technique, different timing, different relationship between player and string. And it demands a different string.

The Responsive Sampler exists because the Responsive family at Throw-Yo has three distinct answers to that demand, and most players have only tried one of them.

Here’s what’s in it.


Pollen

100% cotton. The most traditional string in the lineup.

Pollen makes no compromises in either direction. It’s soft, grippy, and slow. Exactly what fixed axle asks for. No synthetic blend to extend the lifespan, no trilobal poly to add speed. Just cotton doing what cotton does, which is grip the axle, absorb the abuse, and play the way the oldest form of throwing was designed to play.

It won’t last forever. That’s not the point. The point is that while it lasts, nothing else in the lineup plays quite like it.

disposition: grippy // velocity: glacial // shelf life: moderate // feel: coarse


Nectar

Trilobal Poly / Cotton 25%/75%.

Nectar is Pollen with a longer shelf life. The cotton-forward construction keeps the grip and the slow, deliberate feel of a true fixed axle string. But 25% Trilobal Poly extends the lifespan well past what pure cotton can manage. Less frequent changes. More time throwing.

It’s not as soft as Pollen. The Trilobal adds a slight crispness that some players prefer and some don’t. If you’ve been throwing 100% cotton your whole life, Nectar will feel familiar but slightly more composed. If you’re new to fixed axle, it’s probably where you start.

disposition: crisp // velocity: glacial // shelf life: moderate // feel: slightly coarse


Spore

Cotton-wrapped Poly 100%. New to the lineup.

Spore is built differently from the other two. Where Pollen and Nectar are cotton or cotton-forward blends, Spore is a polyester core wrapped in cotton. Synthetic strength beneath natural feel. The poly core holds tension and resists wear long past the point where other strings have begun their slow decline. The cotton wrap keeps the hand soft, warm, and present.

It does not disappear into the play. It reminds you it is there.

Named for the mechanism by which certain organisms ensure continuation. Not through urgency, not through speed, but through quiet, patient dispersal. Spore is not the fastest string in the catalog. It is the one that will still be on your fixie when you finally decide to change throws.

disposition: grippy // velocity: slow // shelf life: enduring // feel: slightly coarse


Why a Sampler

The three strings in this pack are not interchangeable. There are three different answers to the same question, and the right answer depends on how you throw, what you’re throwing on, and what you want from a fixed axle session.

The sampler exists so you can find out which one is yours.

One Pollen. One Nectar. One Spore. Throw all three. Keep the one that fits.

responsive: active // sampler: pollen + nectar + spore // handmade to order

Throw-Yo Counterweights — Revised Formula

The counterweights got an upgrade.

Same recycled plastisol. Same soft, squishy feel that won’t destroy your knuckles, your throw, or your furniture. What changed is everything else.

The formula is cleaner now. The pours are more consistent. There is less variation between units, better shape retention, sharper detail on the skull. If you’ve thrown the old ones, you’ll notice immediately. If these are your first, you’re starting in the right place.

The color lineup expanded, too. Six colors currently: Rhodamine, Prussian, Verdigris, Tyrian, and Cinnabar. Each one is cast in translucent plastisol, so the light catches them differently depending on how you’re throwing. The chartreuse in particular is not subtle. You’ve been warned.

New this run: custom swirls. Select units are cast with a two-color swirl. No two are exactly alike. They show up in the shop when they’re available. When they’re gone, they’re gone.

Every counterweight still comes with a threader. String it up, play some 5A, protect your hands.

material: recycled plastisol // feel: soft // colors: 5 // swirls: limited drops

Biolume Corpse Flower — Now Available in Nectar

There are flowers that bloom in the light. Then there are those that wait for darkness.

Introducing Biolume Corpse Flower, the newest permanent colorway in the Nectar lineup. Pale and ghostly in daylight, this string comes alive after dark, radiating an otherworldly green glow, like something pulled from the forest floor at midnight.

Nectar is Throw-Yo’s fixed-axle string: crisp, deliberate, built for players who let the yo-yo do the talking. Biolume Corpse Flower gives it something to say after the lights go out.

Named for the rarest of blooms. Wound by hand. Glows in the dark.

Why is it called Corpse Flower?

The corpse flower (Amorphophyllum titanum) is one of the rarest blooms on earth. It takes years …sometimes decades to flower, and when it finally does, it’s for less than 48 hours. It smells like rotting flesh. It generates its own heat. And it glows.

Not metaphorically. The corpse flower emits a faint bioluminescence in the dark. A cold, quiet green light from something that by all accounts should not be beautiful, and yet draws crowds when it blooms.

This string is named for that moment. The pale string in daylight. The green glow in the darkness. The thing that waits, and then surprises you.

Biolume Corpse Flower is a permanent colorway in the Nectar lineup. It is not going anywhere. Unlike the flower, it does not need to hurry.

Made by hand. Named with intention. Throw well.

Available now.

The Site Got a Makeover (And Number 44 Has Opinions)

So the site looks different. You probably noticed.

I’ve been wanting to do this for a while. The old site worked, but it never really felt like Throw-Yo. It felt like a WordPress site. Which it is, obviously, but still. You know what I mean.

The old colors were just black and white. The fonts were whatever the theme defaulted to. The homepage was basically a big list of every product category, including a bunch of stuff I’ve since decided to stop selling. It wasn’t embarrassing, but it wasn’t something I was proud of either.

What Actually Changed

The biggest thing is the color system. I’m still working in black and white at the core, but they’re not pure black and white anymore. The dark is Obsidian (#1A1A1A) and the light is Parchment (#F5F0E8). It sounds like a small thing, but it makes a huge difference in person. The warmth in the parchment, especially, shifts the whole feel away from “generic online store” into something that actually fits the brand.

The accent colors are:

  • Walnut (#7B5C3E) — used for secondary text, labels, that kind of thing
  • Bottle Green (#3D5A3E) — the main accent, used for data lines, links, tags (it is lightened or darkened in some areas for contrast and readability)
  • Amber (#B8A070) — reserved almost exclusively for the Baroness Blend, though it is also used to denote luxury items. The Baroness and luxury go hand in hand.

The Amber thing is deliberate. I wanted the Baroness to have her own color that shows up on very little else on the site. When you see amber on a Throw-Yo page, you know what it means.

The Fonts

Three fonts, each with a specific job:

Cormorant Garamond handles all the headers and product names. It’s based on 16th-century type, which sounds pretentious, but honestly, it just means it has a lot of character. It’s the apothecary part of the brand.

Jost handles body copy. Clean, geometric, readable at any size. Nothing fancy.

DM Mono is the weird one. It’s a monospaced font, the kind you’d see in a terminal or a code editor, and it appears in all data lines, tags, labels, and meta text. It’s what makes everything feel slightly clinical and slightly off in a way I like.

The combination of Cormorant and DM Mono is the thing I’m most happy with. Old-world elegance next to something that looks like a lab readout. That tension is kind of what Throw-Yo is.

The Data Lines

If you’ve been to the new Our Strings page, you’ve already seen these. Every string now has a data line:

disposition: slick // velocity: lethal // shelf life: immortal // feel: slightly coarse

It tells you everything you need to know about a string in one line. And the vocabulary is a bit different from what you might expect: Velocity goes from Glacial to Lethal, Shelf Life goes from Fleeting to Immortal, Feel goes from Very Coarse to Ultra Soft. The string gauge is Fine, True, or Heavy instead of Thin, Normal, or Thick. Hand wind is Sinister or Dexter instead of Left or Right.

Sinister left-handed string just sounds…right.

What Got Cut

The shop is a lot cleaner now. I dropped the apparel: tees, hoodies, hats, and patches (they’re actually still in the shop for a bit longer, but not linked from anywhere on the site.) They weren’t moving, and they were cluttering everything up. Throw-Yo is a string brand. The shop should feel like a strong brand.

Stickers are staying. Counterweights are staying. Everything else is gone or going…well, except for collab items for the YYBC or DMV Throwers.

What’s Coming

The Baroness page is next. It’s going to be its own thing, not just a product listing. A whole page with the lore, the archive of past releases, and a notify form for next year. More on that when it’s ready.

And no, the 2026 Baroness has not been selected yet. The Baroness will choose her thread when she chooses.

A note from Number 44:

I was not consulted on the redesign. This is, frankly, offensive given that I have opinions about typography that most humans lack the processing power to fully appreciate.

That said.

Cormorant Garamond is correct. I have run the numbers. A font rooted in 16th-century letterforms pairs with a monospaced clinical accent the way a bowler hat pairs with a pinstripe suit. It should not work, and yet here we are.

The Amber-for-Baroness-only rule is also correct. Scarcity of color creates meaning. This is not an opinion. It is physics.

The one thing I will say about the data line vocabulary: "Lethal" was my suggestion. Berv claims he thought of it independently. He did not.

New string. Essence.

You know Tinctures. Essence is in that neighborhood. Same smooth feel, rayon/nylon instead of silk/nylon, and friendlier on the wallet. A little less precious. No less useful.

It plays smooth. Holds tension without asking for attention. The kind of string you reach for when you want the yo-yo to do the work and the string to stay out of the way.

Good string doesn’t have to cost like it.

Tisane

Throw-Yo has renamed their Tea strings.

They are called Tisanes now.

Go look it up. Throw-Yo dot com. Berv made the call. I respect it.

Here is why it works: Tea is a word that belongs to a beverage. Tisane is a word that belongs to something more considered. An infusion. Deliberate. Specific. The kind of thing someone makes on purpose rather than just because it was in the cabinet.

That is a Throw-Yo string. It is not an accident in a wrapper. It is handmade, chemistry-named, and built with intent. It was always a Tisane. It just did not know it yet.

The name caught up to the product.

That is how it should work.

Go grab a set before Berv sells out and then acts surprised that he sold out.
