Callaway iron
The Callaway Apex Pro 21 iron is an iron in 9 options from 20.5°–50°, RH and LH.
Discontinued. Kept here because the published specs still matter to anyone playing one or buying used.

Where this club lands
The field is every iron in the database that publishes both of the chart's figures — every brand, not just Callaway.
This set's 7-iron is 33° — 72nd percentile, weaker-lofted than 72% of the 889 sets that publish one. The median is 32°.
Loft ladder against the field
Loft at each club in the set over the middle half (p25–p75) of every comparable iron set on record — the busiest rung here is built from 900.
Callaway Apex Pro 21middle half of the field
A break in the line is a club the set does not publish a loft for — it is never bridged, because joining across a gap would draw a loft the manufacturer never stated. Every brand's name for the gap wedge is pooled into one rung, since only 25 of 917 sets publish two of them.

The 7-iron of every comparable iron set on record publishing both loft and lie — 889 of them, binned by density.
Offset
Callaway Apex Pro 21 · 7-iron — the leading edge sits behind the line of the shaft by the published figure, drawn to the scale marked and seen from the toe, which is the one view that shows offset truly: it runs perpendicular to the face, so a picture square to the face would have it pointing at you. The outline is a nominal iron — this database holds no head geometry — so the gap the arrow spans is the only measured thing in the frame. The dashed edge is the median of the 7-iron of 580 iron sets on record that publish one.
Offset through the set, against the field

Head geometry doesn't change with the shaft, so it's stated once. A blank cell means Callaway did not publish that figure — we don't estimate.
Callaway publishes offset in millimetres; the offset (in) column is that figure converted, and Callaway's own is in the column beside it.

- Stock shaft, built.Callaway names no stock shaft for this club on the sources we hold, so there's nothing to link.
The site is in beta and the database is still being built, so expect gaps. Know something we don't? Help us fill it in — a link to where it's published is worth more than anything else you could send.
