How to catalog
your fountain pens.

Why catalog at all?

One pen, one ink, you carry the whole thing in your head. The trouble starts somewhere past a dozen, when the daily carry and the grail and the three you got off the marketplace all blur together. A catalog isn't about looking serious. It's about answering the small, specific questions a pen collection keeps asking.

• Which nib is on this pen right now? You bought it as a Medium, ground it to a cursive italic two years ago, and now you can't remember which of your three similar black pens got the grind. The nib is the pen; the body is just the handle.
• What's inked, and with what? Six pens are loaded. Two have been sitting a month and are due to flush. Without a note, you find out which by uncapping each one over the sink.
• What did this one actually cost? The pen, the nib grind on top, the box and converter, where it came from. The trail you want before you sell, trade, or just settle an argument with yourself.
• What am I not writing with? Most collections have a quiet half that lives in the case and never gets inked. Worth knowing before the next "just one more" purchase.

A catalog answers these in seconds instead of opening every case and uncapping every pen. That's the whole case for keeping one.

What to record for each pen.

You don't need all of this on day one. Add the pen, snap a photo, and let the rest fill in. Over time, a good entry holds the things a pen actually has that a watch or a knife doesn't:

• The nib. Width (EF through broad, or stub and italic), the material (steel, gold, the karat), and any grind — a custom architect, a needlepoint, a cursive italic from a nibmeister. This is the field collectors care about most and the one a generic catalog never has room for.
• The filling system. Cartridge-converter, piston, vacuum filler, eyedropper, or a reservoir system. It decides which inks are safe, how much it holds, and how you flush it.
• The body. Brand, model, material (resin, ebonite, celluloid, urushi), trim, and whether it posts. Limited-edition number if it's a numbered run.
• The ink that's in it. What's loaded now, when you inked it, and the inks that paired well — the shimmer that clogged, the sheen that needed a wet nib, the iron gall you keep away from the piston.
• The history. Purchase date and price, the seller or pen show, whether you have the box and papers, and any nib work: who ground it, when, what you asked for.
• The pictures. The nib under good light, the section, the imprint. A clear shot of a tipping geometry does more for a future sale than a paragraph of description.

That last point earns its keep. A year on, a sharp photo of the nib and the box is what turns a sale or a trade from a back-and-forth into a yes.

Online catalog, rotation tracker, or spreadsheet?

This hobby has real tools built for it, and some of them may suit you better than Hoblio. Here's the honest version of each.

An online pen catalog is where many people land first. The good ones have structured fields for pens, nibs, inks, and shared libraries you can pull from instead of typing every spec. If you want a connected catalog, want to log every ink swatch, and don't mind that it's an online account with your collection on a server, that can be a genuinely good fit.

A rotation tracker takes the narrower, sharper angle: which pen is inked with which ink, right now, and for how long. If your actual pain is the inked-pen rotation and remembering to flush, a dedicated rotation tracker does that one job well.

Simple phone inventories sit closer to Hoblio — a private list of what you own, often with photos and notes. Worth a look if a deep web catalog feels heavier than you need.

A spreadsheet is free, it's yours, and it does exactly what you tell it. Plenty of careful collectors keep one and nothing else. The cost is friction: you build the nib and filling-system columns by hand, photos of the imprint live in some other folder, and pulling it up at a pen show to check if you already own that limited resin model is a small ordeal. If you love spreadsheets you already know this. If you don't, you'll start one, add eight pens, and never open it again.

Where most of these keep your data.

Most web-based pen catalogs run as accounts in the cloud. You sign up, and your list of pens, what you paid, and where you bought them sits on their servers. For a lot of collectors that's a fair trade for the shared database and sync across devices, and there's nothing wrong with taking it.

For others it isn't the trade they want. A full list of every gold-nib pen in the drawer, with prices, is the kind of thing some people would rather not have living behind a login they don't control. Not paranoia — just a preference for a record of what's in the case staying in the case.

Hoblio takes the other side of that. Your shelf lives on your phone, with no account and nothing syncing out. The cost of that choice is real and worth saying plainly: no shared ink library to pull from, no sync to a second device, no community swatches. If those are the features you came for, a cloud catalog is the better tool and you should use it.

Hoblio is not for you if…

A few honest disqualifiers, because a noun-swapped pitch helps no one:

• You want market values or a marketplace. Hoblio shows no valuations and has nothing to sell against. If you're tracking pens as appreciating assets or want to buy and sell, look elsewhere — the pen-show forums and the marketplace apps are built for that and Hoblio isn't.
• You want a shared ink and pen database. Hoblio won't auto-fill a flagship model's specs or hand you a community swatch. You type what you own. A shared library is the reason to choose a cloud catalog over this.
• You want sync across phone, tablet, and laptop. On-device means one device. You can export a backup, but there's no live cloud sync, by design.
• You want reminders to flush or a writing streak. Hoblio doesn't nudge, doesn't count days, and won't tell you a pen is overdue. It's a shelf, not a coach.

What a pen costs to own.

Add what a pen cost, and Hoblio shows what it works out to for each day you've owned it — the price divided by the days, nothing more. The daily writer quietly settles into a number you'd round to nothing. The grail you bought at a show and inked twice stays a larger one. Tap Use on the days you actually write with a pen, and you'll see which ones earn their place in the case and which are admiring the view. No lecture, no streak — just the figures, there when you want them.

A wishlist, kept honest.

The handmade grail you keep going back to look at. The nib grind you want to commission once you've decided on the pen. Keep wanted pens apart from the ones you own, so a want stays a want — and the case only grows when you mean it to.

Yours, and only yours.

Your collection lives on your phone. No account. No cloud. No tracking. Exporting, sharing, feedback, and purchase restore only happen when you choose them. No subscription, either — Hoblio Pro is one price, paid once. And no streaks, no reminders. A pen that's been sitting a month will tell you it's dry the moment you uncap it; it doesn't need the app to nag you first.
