This rare material is not a wood species in its own right, but comes from wood that sank into bogs many centuries ago and has undergone various processes of change in the meantime. This preserves the wood naturally and lastingly. An expressive, dark colour develops due to the tannins in the bog. The scarcity of these tree trunks today makes this material a genuine rarity. The colouring of the wood varies between brown, dark brown and black-brown. To begin with, square timbers are sawn from the few usable trunk sections and then turned out as handles. Several polishes with fine oils provide an additional seal for the surfaces and give them a silky-matt finish.
