Extension ladders help you gain a vertical advantage. The rope that comes attached can be used with modified ninjitsu techniques for "knife on a string", except in our case, it is "ladder on a rope." You should note that these techniques require much strength and years of practice to be effective. Fibreglass ladders are best for combat because you do not have to worry about them conducting electricity, although aluminum is lighter. The "feet" on the bottom can be turned out to create a dual bayonet effect, or folded in if you want blunt trauma injuries.
Personally I prefer the four section folding ladders as they are the most portable and adaptable of all ladders, but as a close second, the caving ladder will allow you all of the advantages of a flexible weapon and the addition of a grappling hook makes it extraordinarily useful for trapping and ensnaring. In a pinch the hooks can also be used for fishing for big things that swim in the sea - your opponent can be used for bait.
