The Grivel North Machine is the ideal tool for technical ice and mixed routes in the mountains. A hammer is essential for setting rap anchors other than V-threads. an Adze is the tool for clearing snow or dinner plates while climbing or chopping a stance. The Carbon shaft is light, warm and reduces vibration. The carbide spike works on ice. The picks are Grivel's forged "ice plus" pick. It also accepts the optional Mixed blade.
