You have not heard of the "coup du savoyard" then, which the instructions tell you about. You bang the bottom end of the thing until it comes loose. It works.
I have heard about it plenty of times and done it myself. It is still an unnecessary frustration to deal with, and sadly it doesn't always work. I have had to use pliers before!
There is also the other extreme of being extremely loose as well. I don't wish to have to use a pouch/elastic band/etc if carried in my pocket but also don't wish to run the risk of cutting my hand again when putting my hand in my pocket. That 'flaw' is why I reground one of the locking collars to have a lock shut function, something which is now added in production (I'm not suggesting that it's my design but more one of those times where people arrive at the same conclusion independently) but I've found the ring doesn't always stay in the locked position.
Still love them though.
