His ghoul mask resembles a leather gimp mask with an eye patch. It bears a lipless mouth with large, gnashing teeth, much like a restrained asylum monster. The bolts sticking out of his neck and the fact that he is an artificial ghoul invoke a Frankenstein-like theme.
As Ken Kaneki, Kaneki does not know of Juuzou. Juuzou however, apparently knew by instinct that the Eyepatch ghoul was the same person as Kaneki even though by that time Kaneki's hair had already turned white, along with the fact that he was donning his mask and Juuzou was observing him on ground running whilst on top of an Aogiri building. This is evidenced by when Juuzou sees him and attempts to remember his name (failing to do so though, as he only remembers that the name starts with a "K") while dragging Yamori's body around. 2b1af7f3a8
