One Swiss Knife in the exact shape of your life.

Twenty copies for twenty grandchildren.

An heirloom that can be a hundred heirlooms without diminishing any of them. That is what a file, unlike a pocket watch, can do.

The old constraint on inheritance was scarcity: one watch, one signet ring, one grandmother's cookbook, and a decision about who got it. A Swiss Knife is not scarce. It is a file. You can copy it once, or a thousand times, and every copy is the whole thing — with the same entries, the same Patina, the same portrait of the life that made it.

How the duplication actually works

Right-click, copy, paste. Onto a USB stick, an SD card, a folder called "for the kids". Repeat as many times as you have kids or grandkids. Every copy weighs the same as the original — a few megabytes, or a few tens of megabytes if you've filled it with a lot of life. Nothing about the file requires "activation" of a copy, because there is nothing to activate.

What each copy inherits

All of it. Every entry you kept. The Patina on every blade — soft where you used it, bright where you didn't. The Garden's blooms and wilts. The whole shape of the life you carried in this Knife. From the moment you hand a copy over, that copy is complete; from the moment the recipient opens it, their own use begins layering on top.

One life, twenty continuations

A pocket watch can only tick on one wrist. A file can tick on twenty. Each grandchild's copy diverges the day they start using it — new entries, new wear, new corners softened — while the record of you sits underneath, unchanged. It is a strange and rather beautiful thing that software can do and physical objects cannot.

No paperwork, no permission

No licence to split. No seat to reassign. No email to the vendor. No probate for a login. The copies exist because you made them, and they will keep opening because HTML keeps opening. That is the whole mechanism.

Common questions

Is there a limit on how many copies I can make?

No. There is no licence key, no per-seat count, no activation server. You own the file the way you own a book — copy it as many times as you like.

Do all copies stay in sync?

No, and that's on purpose. From the moment you copy the file, each copy is independent — the recipient's use lands on their copy, not yours. If you want a single shared record, keep the file in one place.

Can I make copies while I'm still using mine?

Yes. Duplicate the file whenever you like; your copy keeps going, and each duplicate is a complete snapshot at the moment you made it.

Will the copies still work in fifty years?

Every browser ever written can open an HTML file. There is no vendor to disappear and no format to be revoked. As long as browsers exist — and they will — the copies will open.

Do the grandchildren need to buy anything to keep using it?

No. The file they inherit is the whole tool. If they ever want a fresh Knife of their own — different Blades, different shape — that's a new forge at their expense, but the copy you gave them keeps working forever, free of any ongoing fee.
