Well, I got a lot of answers and no one was right. Sixbears (of http://sixbearsinthewoods.blogspot.com/ ) said in his comment that he had "gotten by in life without needing one", and I replied "I would hope so". The Odd Essay of
(http://theoddessay.blogspot.com/) suggested that it was used to plant peas and I told her she was closer to the answer than she knows.
OK, enough delay, since I promised to tell you I guess I have to. So. . . It is a contraption that not only can be used as a cane, it helps the user direct the flow when he has to urinate. I must assume that the user is incapacitated in some way or another or has the shakes and tremors real bad and can not hold steady and needs assistance from a cane while walking and the other questionable part of the cane is for when he has to "go".
OK, now that I got that out of the way (I hoped I explained it properly), I hope none of you need such a tool and that you all have a great day, you hear?
