A sgian without a blade is not a sgian. That has been my philosophy for thirty-three years and will remain so. Of course you have to respect local laws, no matter how silly they may be and, if I ever encounter a jurisdiction where I cannot carry one of my sgians in the top of my hose, then I will go without. So far, I have not spent time in such. When we go back to Scotland in 2018 I may meet up with that for the first time.
