    Where I notice the difference in steel is when using a hack saw to cut ground tackle chain. High test chain is very tough to cut and would present trouble in an emergency should slipping the hook ever become necessary. Standard BBB chain can be cut by hacksaw or bolt cutters with ease.

    Weight is your friend when anchoring until the windlass breaks then it's your enemy. Weight on a bridge is always the enemy so the stronger lighter material understandably gets the nod.

    no idea, not impossible, high tensile steels are, Uhm, less than ideal to work with.
    How hard? I find it hard to express exactly how difficult they can be to work without resorting to quite harsh language, let us just say they require attention and good tools/machines.
    I have worked steel that required the edge to be near perfectly sharpened, a tiny imperfection that would not have mattered machining even 316 stainless or hardened truck springs would make a MESS of this stuff (looked dull and uneven almost like packed silvery sand)
