emma kites 100% Black Kevlar Braided Cord (0.4~4.6mm Dia, 50lb~1800lb) High Strength, Abrasion Flame Resistant, Tough Survival Tactical Cord Model Rocket Paracord Snare Line Fishing Assist Cord

I'm not sure how this string ("Utility Cord") could be used for 'tactical' or 'survival' purposes, but it's certainly strong. I haven't tested the absolute limits but it seems like I could probably use a single length to escape from an upstairs window without a problem (does that count as 'survival'?).As a kite string, you could probably attach a 747 to it and prevent it flying away, so I really can't fault it. Great quality, useful reel, and black so it doesn't look like standard Kevlar. I'm just not sure (yet) how it will stand up to moisture, as woven Kevlar can break down under certain circumstances. However, it does seem to be coated so I'm reasonably optimistic that it'll survive for a while.

This is good strong thread.I purchased the string with a core.After my first try with it, I noticed the knot was becoming a little loose and the ends were becoming frayed. To fix this, I put a tiny drop of glue on the knot and also on the fraying ends. The problem was immediately solved. The ends no longer fray and the knot stays tied.

Does exactly what I need it to do.

amazingly strong for its size
