CHOIL
The collector's knife vault
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
CHOIL is the precision-milled digital vault for knife and EDC collectors.
Catalog every folder, fixed blade, and EDC piece you own, see what your collection is really worth, and go deeper on the steel and craft than any spreadsheet ever could. Built for people who care about the details.
YOUR VAULT
• Log knives, pens, lighters, and more — brand, model, steel, lock, blade geometry, provenance, condition, and photos
• Add a piece fast, your way: snap a photo for AI identification, scan a barcode (free UPC lookup), paste a product link, search the built-in catalog of known models, or enter it by hand
• A live portfolio value that tracks what you've invested vs. what it's worth
• Organize with labels, mark favorites, track quantities, and set maintenance reminders so a blade never goes too long without care
WISHLISTS
• Keep as many wishlists as you want of the knives you're hunting
• Capture wants the same fast ways you log owned pieces — photo, barcode, link, or catalog
• Swipe through a list, share it privately or with a public link, and convert any wishlist item into your vault the moment you buy it
KNOW WHAT IT'S WORTH
• AI-powered valuation grounded in real resale data
• Per-model price intel: typical range, recent sales, floor and ceiling
• Brand resale leaderboards — see which makers actually hold their value
• Drop Watch: follow the models you want and catch new arrivals and price moves
GO DEEPER ON THE STEEL
• A CAD-style blueprint for every blade shape
• The Steel Matrix: edge retention, toughness, corrosion resistance, and sharpenability mapped as a live metallurgy radar
• Compare any two knives head to head
THE CURATOR (AI)
• Ask anything about your collection — gaps, value, what to sell, what's overdue for maintenance — and get answers grounded in your actual vault
• Run an AI Analysis for a scored rating of your collection across seven dimensions, with concrete ways to level it up
SNIPE — LIVE PRICE CHECKS
• Share any product link or screenshot into CHOIL for an instant AI price check — see the typical resale range before you commit
• Watch live sales right inside the app with a floating price ticker over the stream
• Keep tracking from your Lock Screen with a Live Activity
• Bookmark favorite shops and sellers for one-tap access
COMMUNITY
• Trading Post: a community board to list pieces and connect with fellow collectors. CHOIL processes no payments and brokers no sales — any deals are arranged directly between members, off-app.
• Settle the great debates (framelock vs. crossbar, S30V vs. MagnaCut) with the community
• Collection leaderboards, a public showcase for your best pieces, plus friends and direct messaging
