The Cobra AeroJet ONE iron set has published lofts running from 18.5° in the 4-iron to 54° in the sand wedge, with lie angles progressing from 62.5°. A conservative 1° professional loft or lie change is the sensible first move unless a wider safe range is confirmed for the exact head. Bending 1° strong removes about 1° of effective bounce, while 1° weak adds about 1°. For a right-handed player, 1° upright tends to move the start line left and 1° flat tends to move it right. Because this is a ONE Length model, lie and length changes should preserve the single-length fitting concept.

Bendability verdict
The exact one-piece forged construction is not confirmed here. Use a conservative 1° first move and verify the head before larger bends.
Construction: Exact construction not fully documented.

What bending changes
| Adjustment | Typical effect | What to watch |
|---|---|---|
| 1° strong | Lower static loft and about 1° less effective bounce | Lower flight tendency, more digging potential and a smaller gap to the stronger club |
| 1° weak | Higher static loft and about 1° more effective bounce | Higher flight tendency, more sole bounce and a smaller gap to the weaker club |
| 1° upright | For a right-handed golfer the start line generally moves left | Use dynamic lie and start-line evidence rather than trying to cure swing path |
| 1° flat | For a right-handed golfer the start line generally moves right | Left-handed direction is reversed |
Best fitting order
- Measure actual loft and lie before touching the head.
- Confirm the real problem with carry gaps, start line and turf interaction.
- Make the smallest useful change first — usually 1°.
- Re-measure the club after bending.
- Retest the two neighbouring clubs so the fix does not create a new gap.
Disclaimer: Safe bend limits vary by exact construction and condition. Use a qualified fitter and verify the specific head before larger loft or lie changes.
