How can you tell if irons are offset?

You can tell if irons are offset by examining the clubface's position relative to the shaft. In offset irons, the clubface is set back from the shaft, which helps players square the face at impact. Additionally, you can visually compare the alignment of the leading edge of the clubface to the shaft; an offset design will show a noticeable gap. Lastly, checking the manufacturer's specifications or consulting with a professional can confirm the offset measurement.
