Steel comparison
EDC knife steel: S30V vs M390 vs MagnaCut vs 154CM — edge retention vs toughness tradeoff
Carbide volume, toughness scores, corrosion resistance, and when carbon steel still makes sense for an everyday carry user who sharpens regularly.
Why this page exists
Knife forums produce opinions at industrial scale. Steel comparisons are everywhere. What's missing is a frame for the question that actually matters: for your use pattern and sharpening frequency, which steel gives you the best tradeoff?
An M390 blade that's dull because you hate sharpening is worse than an O1 carbon blade that you actually maintain. The best steel is the one that fits your habits — and that requires understanding what each grade is optimizing for.
