I don't know if it is the best way, but unfortunately for me I like cleats on my wading shoes and as a result have stepped on my fly line more than a few times resulting in everything from nicks to COMPLETELY SEVERED fly lines.

For the nicks & cuts, I have found that Loon UV Knot Sense works great. If you don't already have it, buy the kit with the little UV light, it comes in handy.

I put a little dab on the cut and cure it with either sunlight or the UV light. It works FAST and best of all, the small tube of glue and light is small enough to carry around with you for field repairs of everything from fly lines to waders.

I carry mine with me all the time and have used it MANY times!

Good luck!
