How to identify this generation

• An oval gold i3 badge sits above PING on the cavity, with BLADE or O-SIZE lettered below.

What to notice in the specifications

• PING’s Classics page dates the i3 series to 1999. The Blade and O-Size heads share the loft, lie and length shown here but differ in offset and bounce: the 7-iron has 0.07" offset and 7° bounce on the Blade and 0.21" offset and 10.5° bounce on the O-Size.
• PING labels the pitching wedge W and lists U, S and L wedges at 52°, 56° and 60°.
• The later i3+ revision is a different model with its own specifications; it is not covered by this chart.
• The figures come from an Internet Archive capture of PING’s own US page dated 2003-09-08. The introduction year comes from that page; individual clubs may have been built later.
• Lie angles are PING’s standard specification for the black colour-code dot. PING fits lie angle with a colour-coded dot, so check the dot on a used PING iron against PING’s colour code chart before assuming these lies.
• PING labels the 47° pitching wedge “W”; it is shown as PW here so it lines up with other sets.
