I am selling these items due to my retirement from climbing. * I received these from a friend, but I never actually did any ice climbing, so I am selling them. * I have almost no knowledge of ice climbing, so I may not be able to answer your questions. * Both are from the manufacturer DMM. * The included bag has hydrolyzed and is sticky. An Allen wrench for adjustment is inside. The blades are dangerous if left exposed, so I will ship them in a case. Due to the nature of the product, please understand that these are used items and use them entirely at your own risk. I am not responsible for any injuries that may occur during use. <Additional Information> I have separated the Simond piolet and sold them separately.
