Recently had a few of these break off when on a fish. Using Yo-Zuri 20 lb fluoro, Catch 80g kabura, Uni-knot.
Symptoms: beginner fishing and gets a hook-up on a decent but not large snapper, likely 45-50cm (that's decent where i fish). Line parts relatively early. It isn't the knot, but there is a curled end to the line as if the line gave way just at the knot.
After the second loss I checked the knot every time the lure came back on board but could see no problems. Then lost a third one
Whats happening? Sharp edge on the kabura maybe, so that when the fish shakes its head it cut off the line?
Solution? Heavier leader? But then it doesn't slide through the head as easily.
New problem for me, since I have been fishing those lures for years and my knots don't give way so much these days.....
Any suggestions welcome
