More details about the The Uni Knot
Uses: The Uni Knot is also known as the "Duncan Knot" after its inventor Norman Duncan and as the "Grinner Knot". It was popularized as the Uni Knot by the Miami Herald in the 1960's as a versatile knot which can be adapted to many purposes including snelling; connecting hooks, swivels and lures with a loop; and joining two lines.
Versatile: The Uni Knot is the key component of the Uni Knot System - intended to provide all of the required fishing knots with a single knot.
Tying it: The version shown here is tied to an eye. It can be left as an open loop or snugged down agaainst the hook. When used for joining two lines, each knot is made round the other standing end.
Advantages: It is fairly easy to tie in the dark with practice. Claims that it retains a high proportion of line strength have been disputed. When tied round a large diameter eye, it may retain strength well, but if used to join two lines, like other knots where a line passes round itself, a breaking strain of 50% of ideal performance is more likely. It works well with both braided and monofilament fishing lines.
