Just picked up a pair of used Black Diamond Cobra ice tools (don't worry I know the seller and they've been gently used). These tools are pre-fang handrest and don;t have the bolt hole to take the newer fang. So I'm wondering if anyone has had any luck fitting another manufacturers rest onto this generation of tool?
In reply to Wild Isle: If i remember correctly the old style Viper strike can fit, as it just wraps around the shaft in a jubilee clip stylee!, but not the fang, they were different.
I would say trial and error, but try petzl trigrest first they currently seem to be most adaptable, but possibly an old grivel horn would fit? not sure sorry, I dont remember seeing any with adaptions on at all
