I've had a bit of bad luck, my axe was dislodged by the wind/spindrift at the top of the Message and managed to unclip itself from the clipper leash when it fell.
It's a Black Diamond Fuel Axe (black with a bright green rubber handle).
I think it landed on the ledge before the very last corner of the Message but the weather was too wild to retrieve it this afternoon.
If anyone climbs The Message in the next few days and finds my axe then please get in touch. I'll happily give you a suitable reward
