A story:
Last year I was traveling up an escalator with JRex on my arm and at the top, there was a man with his 9 year old son.
His 9 year old had gotten his shoe lace caught in the escalator between the stairs and the upper floor.
People were starting to trip and fall down at the second floor because they could not get him free.
They were stuck there. The only option for them was to leave the shoe until I arrived at the top.
Seeing the predicament he was in about half way up the escalator, I was prepared when I got to the top.
I asked the father if he just wanted to "cut" the child free and he said yes.
I was ready for the challenge.
I whipped out my pocket knife, cut the child's shoe lace as close to the end as I could and saved the day.
I will never be without a pocket knife of some sort.
