Kallis was made from purchased elm wood.
As beautiful and pleasant as elm wood is, its history of the elm tree is tragic. In England, it became increasingly rare after a fungus was introduced in the 1970s. Today, there are no more old elms to be found in Germany either. It is in the process of dying out across Europe. The “helplessness of trees and humans in the face of elm decline is testimony to the insidious danger that can emanate from introduced animal and plant species or fungi in native ecosystems. In addition, the fatal interaction of fungus and beetle for the elms is an example of the complex interrelationships in nature, which, once disturbed by human activity, can no longer be reversed despite all efforts.” From: https://www.waldwissen.net/waldwirtschaft/schaden/pilze_nematoden/wuh_ulmensterben/index_DE
The name is derived from the ancient Greek Kalliopeia: the one with the beautiful voice and from Kalliope, the mother of Orpheus and the muse of science and philosophy.
