For comparison purposes I weighed and measured the adjustable aluminum cane that I have here.

It weighs 10.5 ounces and will adjust from 30" to 39" long. It easily comes apart and then consists of 2 pieces that are each a little less than 21" long.

If one was flying I think they would allow the cane to be carried on intact.

If one wanted to pack the cane into suitcase or backpack the 21 inch disassembled length would work well.

The cane is very strong, will carry a lot of weight and gives no indication that it would ever slip from the adjusted position.

On a side note, my wife doesn't want me to take it on the trail because it makes me look even older than I am. I like the idea of using it and was thinking that I might take one of those self defense classes called canefu (sp?).
