If you bought an early ChalkBlaster, you picked a size and you picked a bristle. Large or small. Boar or nylon. Four combinations, all on the shelf from day one. That felt like the smart, customer-friendly thing to do. It was the dumbest mistake we made with the first product.
Why four versions felt like a good idea
The thinking was simple. Climbers are picky about brushes. Boulderers want a big head for slopers. Route climbers want something small that fits a chalk bag. Outdoor climbers swear by boar bristles for rock. Gym climbers often prefer nylon. So why choose for them? Give them options, cover every use case, and the ChalkBlaster sells itself to everyone.
Underneath that was a design philosophy we were proud of: everything modular. More flexibility, more value. We thought the modular approach was what made ChalkBlaster clever.
What four versions actually cost us
Four versions didn't mean four products. It meant four of every problem. Four bristle inserts to source instead of one, from suppliers that ranged from reliable to sketchy. Four sets of tolerances to check, because a boar insert and a nylon insert don't behave the same way when you press them into a head. Four quality-control checklists, four packaging variants, and four ways for an order to go wrong.
And every one of those multiplied the time between "we're ready" and "it's in a climber's hands". Harder to find suppliers. Different quality issues per version. Slower time to market, on a product that was already the first of its kind and had no playbook.
The real mistake was the philosophy, not the lineup
Looking back, the four versions were a symptom. The disease was "more flexibility equals more value". Flexibility opened too many doors at once. Instead of nailing one ChalkBlaster that solved the core problem, clearing chalk off a hold fast, we tried to be everything to every climber before we'd proven the one thing.
The variations could have waited. Nobody buys an electric brush because it comes in two sizes. They buy it because the hold is clean in two seconds. Prove that with one product, then earn the right to add options.
Large and small, boar and nylon
Four supplier chains
Four sets of QC issues
Slower to market
One core product, nailed
One insert process, consistent fit
Options only once the core is proven
Faster from workshop to chalk bag
What this means for your ChalkBlaster
ChalkBlaster V2 is being built the other way round. One handle, one jet fan, one brush head design that we've obsessed over, with the insert made by one process so every head fits the same way. Fewer variants means every unit gets more attention, suppliers get bigger and more consistent orders, and the thing you hold has been tested a thousand times instead of two hundred and fifty times across four versions.
Options aren't bad. Options before the core is right are. We learned that the expensive way so the next ChalkBlaster in your bag doesn't have to.

Quick answers
I have a small ChalkBlaster with nylon bristles. Is it worse?
No. All four early versions clear chalk the same way. The mistake was on our side of the bench, in how much harder four versions made it to build and ship them well.
Will ChalkBlaster V2 come in sizes?
V2 starts as one product that does the core job as well as we can make it. Anything beyond that comes after, once climbers have told us what they actually miss.
Can I still choose boar or nylon?
Brush heads on ChalkBlaster are swappable, so the bristle choice lives in the head, not in which handle you bought. That's the part of modular that was worth keeping.
