In reply to durgun_oguz:
The Grivel North Machine has two (four if you include Mixed) types of pick. The ice blade pick
does not have the attachedment for the Adze and Hammer and the Ice blade Plus which does have the attachement for the Adze and Hammer.
If you are asking about removing the adze and hammer then assuming you have the "plus" pick you simply remove the two small bolts attaching them with an allen key and a socket or spanner on the bolt.
If you do this you will still have the piece of the blade on the back of the axe head that they attach to this cannot be removed as it is an integrale part of the pick.
So you if you do not want any attachements the best way would be to buy the ice pick that does not feature the spur for the attachements and either sell the others or keep them as spares.
