A knife collection app for people who actually carry them
A good knife has a history: where it came from, what steel it is, when you last sharpened it and how it has changed with use. A tidy catalogue makes it easy to see what you own, what you carry and what needs care.
Record the specs once
Write down the maker and model, blade length, blade steel, lock type and handle material when you buy the knife. These are the details you will otherwise look up again each time someone asks, and they matter when you compare two knives you are deciding between.
Keep a care log
Note when you sharpen, what you used and what edge angle you aimed for. Add oil or pivot cleaning if you do it. A short log helps you see which knives are getting used and which sit in a drawer.
Know the rules where you carry
Rules about carrying knives differ a lot between countries and even between cities, including blade length and locking mechanisms. Check the law wherever you carry, and keep a note of anything you need to remember about each knife.
What to record for each knife
| Item | Why it matters |
|---|---|
| Maker, model, year | Variants and production runs differ, and so does their value. |
| Blade length and steel | The core of what the knife can do. |
| Lock and handle material | Helps you compare and spot wear. |
| Purchase date, source, price | Your own history and proof of ownership. |
| Serial or limited-run number | Collectors want it; keep it private. |
| Sharpening and care log | Shows what is in rotation. |
How LAYX handles this
- A private Vault with a category for knives, with photos and close-ups for each one.
- Sealed details (serial number, price, receipts) are encrypted on your phone; only you can read them.
- An optional morning Drop of what you are carrying today. Nothing for sale: buying, selling and trading are not allowed in the app.
Get notified when LAYX launches
One email when the app is approved on the App Store and Google Play. Nothing else.
Questions
Can I sell knives through LAYX?
No. LAYX is a private catalogue and a morning photo, not a marketplace.
Does LAYX cover firearms?
Hunting and sport shooting live in a separate Field space that is off by default and only for adults who confirm that they legally own what they post. Buying, selling, ammunition sales and modification guides are not allowed.
