What the differences mean
Every club the two sets share has exactly the same loft, starting with a 34.5° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show. Lie angles and lengths match as well, so any fitting adjustment made to one set would carry straight over to the other.
The sets are built differently: the i3 O-Size runs 3-iron to LW (11 clubs), the i3 Blade 1-iron to LW (13 clubs).
The i3 O-Size is a game improvement iron and the i3 Blade a blade iron, so they sit 3 steps apart on the forgiveness scale. The i3 O-Size is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The i3 Blade trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits low single-digit handicaps who strike the ball consistently.
Both heads are listed as investment cast. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The i3 Blade came out 1 year after the i3 O-Size, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The i3 O-Size and i3 Blade share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
