Throw-Yo Threads — String Reference
Handmade in Connecticut. One string at a time. Made when you order it.
Every blend is wound-by-hand by Berv Throwington; available for righties and lefties, in standard 120cm or long 150cm. Strings are made to order. Check the String Queue before buying.
“Berv makes the string. You throw the string. I judge the string. This is the natural order.”

String Families
Throw-Yo strings are organized into four families based on how they play and feel. Pick the family first. Then pick the blend.
Comfort
Soft, forgiving, and built around how a string feels in the hand first.
disposition: plush-to-normal // velocity: slow-to-moderate // feel: soft-to-ultra-soft
Tincture (Luxury) — Silk / Wooly Nylon 25%/75%
The everyday string with no compromises. Ultra soft, enduring shelf life, brisk enough to keep up. If you only own one Throw-Yo string, this is the one.
disposition: normal // velocity: brisk // shelf life: enduring // feel: ultra soft
Serum — Wooly Nylon 100%
Made solely for comfort. Plush on the finger, unhurried in play. Long sessions. No complaints.
disposition: plush // velocity: moderate // shelf life: moderate // feel: ultra soft
Vapor — Trilobal Poly / Wooly Nylon 50%/50%
The comfort blend with enough speed to stay interesting. Very soft. Solid whips and slacks.
disposition: normal // velocity: moderate // shelf life: lasting // feel: very soft
Tisane — Wooly Nylon / Bonded Nylon 80%/20%
Slow, grippy, and extremely stable. If you want deliberate play and a string that holds its shape, this is it.
disposition: grippy // velocity: slow // shelf life: enduring // feel: soft
Essence — Rayon / Wooly Nylon 25%/75%
Plush with a bit of structure. The bridge between Comfort and Performance for players who want both.
disposition: plush // velocity: moderate // shelf life: lasting // feel: soft
Performance
Speed, snap, and technical play. These strings were designed to get out of the way.
disposition: slick-to-crisp // velocity: brisk-to-lethal // feel: soft-to-slightly-coarse
“Performance strings are for people who treat yo-yoing like a precision sport. You know who you are. I respect it. Barely.”

Ink — Rayon / Trilobal Poly 50%/50%
Lethal velocity. Immortal shelf life. Killer whips and slacks. The flagship Performance string and the one that started the conversation.
disposition: slick // velocity: lethal // shelf life: immortal // feel: slightly coarse
Detergent — Rayon 100%
Slick, fast, and somehow soft. Gains and loses torsion faster than most — stay on top of it.
disposition: slick // velocity: lethal // shelf life: immortal // feel: soft
Elixir — Trilobal Poly 100%
Crisp response. Immortal life. The technical player’s workhorse.
disposition: crisp // velocity: fast // shelf life: immortal // feel: slightly coarse
Ether — Trilobal Poly / Spun Poly 50%/50%
A step above Solvent in every direction. Brisk, lasting, reliable.
disposition: normal // velocity: brisk // shelf life: lasting // feel: slightly coarse
Solvent — Spun Poly 100%
Standard spun poly, wound tighter. Better torsion hold. Snappier bind. A familiar feel made better.
disposition: normal // velocity: moderate // shelf life: moderate // feel: slightly coarse
Catalyst — Invisible Nylon / Wooly Nylon 50%/50%
Bouncy and brisk. More lively than Serum, softer than Elixir. The Performance entry point for players coming from Comfort.
disposition: bouncy // velocity: brisk // shelf life: lasting // feel: soft
Responsive
Fixed-axle and responsive play. Grip is the priority. Forgiveness is built in.
disposition: grippy-to-normal // velocity: glacial-to-slow // feel: soft-to-coarse
“Fixed axle. The ancient discipline. The humbling art. Berv has been practicing it for years and remains, heroically, terrible at it. The strings are not the problem.”

Honey (Luxury) — Cotton / Silk 75%/25%
The premium fixed-axle option. Buttery smooth, soft on the finger, slow and deliberate in play.
disposition: normal // velocity: slow // shelf life: lasting // feel: soft
Nectar — Trilobal Poly / Cotton 25%/75%
Cotton-forward for fixed axle, with enough Trilobal Poly to extend the lifespan past what pure cotton can manage.
disposition: crisp // velocity: glacial // shelf life: moderate // feel: slightly coarse
Pollen — Cotton 100%
Pure cotton. Pure fixed axle. No compromises, no synthetic additions. The most traditional string in the lineup.
disposition: grippy // velocity: glacial // shelf life: moderate // feel: coarse
Specials
Limited releases, collaborations, and commissioned work. Outside the main catalogue.
Night Soil — Rayon / Trilobal Polyester / Wooly Nylon 40%/50%/10%
A collab blend created for Audrey Sickburn’s Waffle Stomper yo-yo. Slick, brisk, and built for technical play. The precedent for all future Throw-Yo collabs.
disposition: slick // velocity: brisk // shelf life: enduring // feel: slightly coarse
Current Night Soils: Poo’n’corn · Bloody Disgusting · Barium Enema · Mint Cocoa

The Baroness Blend
“Once a year, The Baroness walks into the thread room and picks a spool. She doesn’t throw. She has taste, which is rarer. Berv winds it. I observe. The community buys it. This is the one Throw-Yo product I have no notes on.”
— 44
The annual limited release. Selected every year by The Baroness — Berv’s wife — who chooses the thread entirely on her own terms. Berv winds it. Whatever comes out gets her name.
The first Baroness Blend was the Baroness Special Ink (2025): 75% Trilobal Poly / 25% Rayon in purple, pink, and teal. It sold out.
The 2026 Baroness has not yet been selected.
Counterweights
Handmade from recycled plastisol. Soft, squishy, and genuinely good for your knuckles, your throws, and your furniture. Each counterweight comes with a threader. String it up. Play 5A.
Resin counterweights appear occasionally on a limited basis.
Current Colorways
Colorways rotate regularly. Check throw-yo.com or the shop for what’s currently available. Monocolor is always in stock for every blend.
Gauge, Hand, and Length
Every string is available in three gauges and two hand winds:
| Fine | Thin profile. More gap clearance, lighter feel. |
| True | Standard profile. The Throw-Yo baseline. |
| Heavy | Thick profile. Fuller feel, tighter response. |
| Dexter | Right-handed wind. |
| Sinister | Left-handed wind. |
Standard length is ~120cm. Long option (~150cm) available on most blends.
