As long as the blade that cuts is small it's ok. Go onto TSA website. There is an area to look it up. If it isn't there you can message them a pict of it. They will get back within a few days to let you know if you can carry it on to the plane.
I am in the planning stage since I will be having knee surgery next month. What is your sleeping bag that weights 1 lb? I've been looking for lightweight options.
Thanks
