Online Tools & Generators – Other Tools Hub

Not every question fits neatly into a calculator. Sometimes you need a quiz to point you in the right direction, a generator to spark an idea or a straight comparison to settle a debate. 

That's exactly what the Other Tools Hub is for, a free collection of quizzes, generators and comparison tools for the hobbies and questions that don't always show up in a typical calculator directory.

If you're getting into blade sharpening, the two tools here take the guesswork out of getting started. 

The Whetstone Grit Progression Quiz walks you through a few quick questions and tells you exactly which grit sequence to build your sharpening kit around, whether you're maintaining kitchen knives or restoring an old edge tool. 

Once you know your progression, the Water Stones vs Diamond Plates comparison tool breaks down the real cost differences between the two systems so you can decide which one actually fits your budget and how often you sharpen, instead of guessing based on forum opinions.

Crafters get some love too. The Yarn Weight to Hook & Needle Size converter solves one of the most common headaches in knitting and crochet, matching yarn weight to the correct hook or needle size across US, UK, EU, and JP sizing standards. 

No more digging through pattern notes or guessing whether a "worsted weight" pattern from one country lines up with your needles from another.

Tabletop gamers running low on prep time will want the D&D Side Quest Generator. It creates a free side quest scaled to your party's level in seconds, perfect for filling a session, rescuing a game night that's running short on content or just getting unstuck as a dungeon master without spending an hour building an encounter from scratch.

Thinking about an exotic pet? The Beginner Tarantula Species Quiz asks a few simple questions about your experience level and what you're looking for in a pet, then matches you with tarantula species that are actually manageable for a first time keeper instead of leaving you to sort through care sheets for species that are notoriously difficult to handle.

And for the home brewers experimenting with kombucha, the Kombucha Second Fermentation Flavor Combo Generator takes the trial and error out of flavoring. 

It generates fresh flavor combination ideas for your second fermentation, so you're not stuck making the same ginger-lemon batch every single time.

Like everything on SpeedCalcs, every tool in this hub is completely free, gives you an instant result and requires no sign up or account. 

No paywalls, no apps to download, just quick, useful tools for the specific questions that brought you here. Explore the full collection above and find the one that fits what you're working on.
