Most people use a fake plastic knife to get around Scottish restrictions on carrying blades. A bigger concern is that most sporrans are made out of sealskin, which is effectively impossible to take into the US. The one time I looked at taking my kilt with me to the US I decided it would be much easier to buy an all-leather sporran, even though they don't look as nice. Here, at least, a full dress kilt is acceptable as 'black tie' in place of a tux.
