Sheet Bend (Weaver's Knot)
Sheet Bend TyingForm a bight in the thicker rope (blue) and hold it in one hand. Pass the thinner rope (red) through the bight and behind the (blue) tail and standing ends in that order. Finally, tuck the smaller rope under itself to finish the knot.
Sheet Bend (Weaver's Knot) Details
Uses: The Sheet Bend (ABOK # 1431, p 262) or Weaver's Knot (ABOK # 485, p 78) is recommended for joining two ropes of unequal size. The thicker rope must be used for the simple bight as shown. However, it works equally well if the ropes are of the same size.
Becket Hitch: The Becket Hitch is a very similar knot. However, it is a "Hitch": it does not join two ropes, it attaches a rope to a Becket (a rope handle or an eye). In the animation the Blue Rope would be Becket and the Red Rope would be tied to it with a Becket Hitch.
Tying it: The Sheet Bend would replace the Square (Reef) knot except that it is not a binding knot – both ends must be loose in your hands with no load on the ropes. (The Square Knot - with all its faults - can be tied tight against a sail, or parcel, and usually stays tight while the second Half Hitch is tied). The Weaver's Knot is tied in various ways. One way is shown here. A slip knot or noose is tied in the end of the wool. The new piece is threaded through the loop. Pulling on the Noose ends draws the new piece in.
Double Sheet Bend: When the ropes are markedly different in size, the tail of the smaller rope can be taken twice round the bight in the larger rope to create the double sheet bend.
Structure: When correctly tied the two tails lie on the same side of the knot. The alternative version - with the tails on opposite sides - is less reliable.
Knots for Making a Net: Making a Cargo Net is tedious, time-consuming, and only to be undertaken out of necessity or by the enthusiast.
The image on the left shows the two knots that are most commonly used at each junction when making a net. The Carrick Bend has been used in the upper row and the Sheet Bend has been used in the lower row.
Suggested Scheme for Making a Climbing Net: In case you ignore this excellent advice, and proceed to make your own net, the image on the right shows a method using the the Carrick Bend.
Disclaimer: Any activity that involves ropes is potentially hazardous. Lives may be at risk - possibly your own. Considerable attention and effort have been made to ensure that these descriptions are accurate. However, many critical factors cannot be controlled, including: the choice of materials; the age, size, and condition of ropes; and the accuracy with which these descriptions have been followed.
