Agree that you need to have some time and space to get familiar with the proper use of the Corkscrew.
Do not wear the Corkscrew thru TSA or you will be pulled aside and searched for carrying a large metallic device in your pants.
The Corkscrews are made for maximum weight at a given size. However if you prefer a smaller lighter device it also includes a PVC end cap for sealing the wire after removing coils.
I personally prefer a lighter Corkscrew with 2 coils removed for the overall comfort and convenience that it offers over the weight of the full size unit. Worn this way the coils can be spread apart for the mechanical forces of extension to be applied.
You should not take this suggestion as an insult but rather an opportunity to experiment and find ways to get the best performance out of the device.
