The Fritz handle was invented specifically for cane users with painful hands, as in arthritis. A German Count is credited with this increasingly-ergonomic handle that eliminated pressure points in the middle part of the hand. The derby and crook cane, due to their ‘hump’ shape, press in there, and can really hurt when leaned on hard. When you look at the Fritz handle, you can see how straight the top is, which makes it more comfortable. Definitely an improvement for those who depend on a cane for constant support when walking.
Walking cane handles have advanced to being made specifically for left hand or right hand use, a boon for those who only use one hand anyway, and much more comfortable when there is consistant use. Try a few out when you can, until you find the perfect walking cane handle for your use!
