Your blades are premium.
Your vault should be, too.
Blueprint spec sheets, live metallurgy vectors, and real sold-comp values for every folder and fixed blade you own — with an AI curator that knows your collection cold.
Unlimited knives. Cloud-backed and synced across phone and web — free, always.
Know what it's worth before the hammer drops.
Snipe is CHOIL's browser extension for live auctions. It reads the lot as it comes up and pins our real sold-comp value right next to the stream — median, range, and a deal meter that flips green the second the bid is a steal. Works on Whatnot and eBay — or right-click to price a knife on any page.
CHOIL for iPhone & Android.
The full vault in your pocket. The native apps are live on the App Store and Google Play now — build out your collection on the web and pick up right where you left off. Turn on Offline access to keep a read-only copy on your device; CHOIL refreshes it when the app detects a reconnection or starts online, with a manual Refresh in Settings as backup. Pull down on vault and wishlist pages to check for web changes immediately. Photos taken from a knife's Photos screen can be cropped, rotated, tuned, and filtered before upload. Every record also gets a permanent inventory number, with Avery 5160/5163 and thermal-roll label printing for its box — and scanning that label's QR opens the record right in the app. Have a spreadsheet already? Import it in one paste.
Steel vectors, not steel marketing.
Every blade in your vault renders a live performance polygon. Compare against the S30V baseline — or any steel — and see edge retention, toughness, corrosion resistance, and sharpenability snap into focus.
Larrin Thomas' balanced wonder-steel. The new baseline.
- EDGE+1.5
- TOUGH+3.5
- CORR+1.5
- SHARP+1.0
The UI anodizes to your gear.
Carbon-fiber scales drop a 5% twill weave into the background. Raw titanium clears it and shifts the accent to electric blue. Zirconium pulls in iridescence.
Saves feel like lockup.
Haptic detent click on save. Spring-physics modals that snap like a perfectly tuned frame-lock. Zero blade play in the interaction model.
Sold prices, not asking prices.
Our proprietary process pulls completed secondary-market sales, throws out IQR outliers, and writes a median to each piece. Your portfolio ticks like a trading terminal.
Know what holds value — and what just dropped.
CHOIL tracks real completed-sale prices so you can see which brands and models actually hold their value. Follow brands and stores, paste any product link to import it, and get pinged the moment a watched piece comes back in stock.
An AI that actually knows your gear.
Values every piece from real sold comps, fills in factory specs, hunts down a product photo, and writes a blunt read on your whole collection — its strengths, its gaps, and the one piece that would level it up. Then ask it anything about your vault.
Seller titled it "CUSTOM DROP"? One click identifies the knife on sight.
On live-shopping streams where lots close in sixty seconds, Snipe reads each lot as it comes up and pins CHOIL's sold-comps value next to the stream — median, range, and a live deal meter on the current bid. When the title tells you nothing, you box the item on screen and the AI uses the image plus the page's available item details to make its best identification.
Snipe uses our best efforts to identify items from what's on screen, but we can't and don't guarantee it will always identify a lot, or identify it correctly. Values are estimates, not appraisals — always verify before you bid.
Whose collection wins? Let the AI call it.
Put two vaults head-to-head. The AI scores both on steel, brand caliber, diversity, rarity and more, picks a winner with a reasoned verdict, and tells each of you the next piece to chase. Share the result with a public link — bragging rights, receipts included.
A members' trading post — never a checkout.
Post what you're hunting, what you'd let go, or what you'd trade — and attach a piece straight from your vault. Deals happen directly between members; CHOIL never touches the money. Community-moderated, with admin appeals, so it stays civil.
The vault now sells the knife, too.
Flip a piece to availableand it appears in The Case — the members' storefront — with no listing to write. Or let CHOIL build the eBay listing from the piece's own record: draft first, publish only when you confirm. When it sells, log what you actually netted, print a Bill of Sale, and hand the piece's provenance chain to its next owner.
