Before covid-19, pretty frequently. For instance, I once noticed that the end of my shoelace broke off. If you want to prevent continued fraying, you can use a lighter to melt the end of the lace. Besides that it's a well-designed, classic looking, functional tool that I enjoy handling.

I live in New York, where smoking is more common, and I've found an abundance of social situations that become available when a stranger needs a light.
