I saw this, this morning on Facebook. Very interesting. Having shattered my hip badly years ago, I get arthritis pains when the weather is just right, and I have to walk with a cane. The idea appeals to me, but I can't imagine putting my weight on the stummel of a pipe at that angle. It would have to be one fat and strong stem. Plus, I think the that the taper from stummel to the shaft of the cane looks OFF to me, like too much of the pipe sticks out. I would love one of these, but only if the stummel better fit down into the shaft, with some way to not leave so much of the stem sticking out of the shaft of the cane, with maybe just a little support surrounding the stummel. But, it would require a bit more artisanry on the part of the maker.
