I am not nearly as versed as I should be in various knots. I am working on a design for a survival pack cloth. Likely to be a large size. Waterproof and uses only limited by your imagination. The amount of usable information you might find on such a thing is somewhat limited. One of the key elements that I think could be of huge benefit AND could be shown in text and/or pictures is knots. There are so many variations. So, what are the important ones? If I go listing 25 knots, its going to take up a huge amount of space. That might be okay if there is really need for 25. What are the "need to know" and would be "handy to know" lists. Bends - Joining two ropes together Figure 8 Bend - Strong and secure joining of ropes the same size. Not Easy to remove Double Sheet Bend - joining two ropes of different size securely Carrick Bend/Pretzel Knot - Joining two heavy lines Water knot - Temporarily secure joining of two rope ends the same size Zepplin Bend - possibly cut all the rest for this one? best all around Lashing - Structure Building Ties Double Constrictor - Basically permanent lashing around round objects Diagonal - Clove Hitch, wrap, clove hitch Square - Clove Hitch, wrap, clove hitch Tripod - Clove Hitch, wrap, clove hitch Shear - Clove Hitch, wrap, clove hitch Hitches - finishing attachment and mechanical advantage Trucker's Hitch - Mechanical advantage on lines that need to be very tight Timber Hitch - tying temporarily to a round object to create a hold Barrel hitch - Keeping an open container upright for hoisting Buntline Hitch - Small and secure end attachment knot. does not create a roomy loop Tight Line Hitch - Load bearing lines with the ability to adjust them periodically Loops Figure 8 Follow Through - Secure End of rope loop Bowline - fixed loop at the end of a line - prob cut this for the figure 8 Prusik Friction hitch - creating a loop on a line with a new line Marlin Spike - temporarily in line toggle Alpine Butterfly - Adding an in line loop good for unidirectional loading Fishing Clinch Knot - line to lure attachment Blood Knot - broken fine line mending Stoppers Simple Double Overhand, Figure 8, Slip knot, Ashley Some redundancies here I suppose. Stuff that should be removed? added?
