Beautiful antique Wenger Tahara pocket knife.  It is in extremely well preserved condition.  Full blade.  The covers appear to be faux tortoise shell.  Tahara was registered as a trademark in 1910.  The name was chosen by the owners wife.  It refers to a Tibetan goddess and translates roughly to "she who saves".  The knife is a rare antique that is uncommonly well preserved. Wenger was acquired by Victorinox in 2005 and beginning in 2013 all of the knives are now branded Victorinox.
