Hello guys, I am writing you with regard to the Grivel Tech Machine Carbon. I own a pair of these tools, purchased in Chamonix in 2016 and I have used them for 2 seasons, mostly for ice climbing and very little mixt climbing. The issue which has come to my attention recently is a delamination/bubbling of the carbon wrap on the handle, in 4 areas - please the attached video - https://youtu.be/A-tbiLyG0A0 I have failed to notice that bulging of the carbon fibre outer shell until now, or at least I don't have any recollection of the issue in the past. I must mention that only one of the axes presents this issue, the other one is completely fine. I have always used the tools with great care, without using or hitting them in any other way than intended. My concern is that this delamination might continue to expand and eventually appear on the entire length of the handle. Could you provide some advice/help/insights regarding this issue? Should I be concerned by this issue or it won't affect the ice axe in any way? Thank you for your help, looking forward to hearing back from you. Kind regards, Andrei
