There's the rub. More often than not, when buying a tool, you won't know. Unless you ask the person/company that you're buying from, and even they might not know (hopefully, if they're also the manufacturer, they will). You (normally) can't tell by looking at the tool. One method is to "spark test" it -- put the tool up to a grinder and observe the sparks. The higher the carbon, the shorter the spark, the lower the carbon, a longer the spark. Get a file, and a large nail from the hardware store, then run each against a grinder. You'll see the file throw what I'm referring to as short sparks, while the nail will be longer (files are usually O-1 tool steel, while nails are A36). Even this method isn't perfect, but its a good general way of telling.
