Knife Steel Atlas

Build your knife collection, scan barcodes and box labels, compare steels, explore knife data, and learn more about the materials behind your blades.

Knife Steel Atlas is a comprehensive knife reference and collection app built to make blade materials, knife specifications, and your personal collection easier to explore and understand.

EXPLORE THE ATLAS

Search and browse blade materials including popular steels such as CPM MagnaCut, CPM 3V, M390, S35VN, and many specialty alloys and blade materials.

Material pages bring together Atlas Ratings, technical performance, typical hardness ranges, material families, application scores, composition information, research confidence, strengths, tradeoffs, care guidance, and detailed material stories.

FIND THE RIGHT STEEL

Tell the Steel Finder what matters to you. Choose priorities such as everyday carry, hard use, saltwater, kitchen use, easy sharpening, long edge life, or collecting to find materials suited to your priorities.

COMPARE MATERIALS

Compare blade materials side by side across technical performance and real-world knife applications. See where each material excels and understand the tradeoffs between them.

BUILD YOUR KNIFE COLLECTION

Create a personal catalog of your knives with photos and detailed information. Browse supported knife makes, models, variants, and configurations to help identify the exact knife you own.

Track details including blade steel, blade finish, handle materials, colors, notes, purchase price, current value, and other available knife information.

SCAN BARCODES

Scan supported UPC and EAN barcodes to search the Knife Steel Atlas knife catalog and quickly identify matching knives. Manufacturer SKU information can also help narrow catalog matches when available.

SCAN BOX LABELS

Use the Box Label Scanner to identify knives from the information printed on their packaging. Knife Steel Atlas uses on-device text recognition to read model names, SKUs, and other label details, then searches the catalog for likely matches.

You can review the recognized text, correct it when needed, and choose the best matching knife from the results.
