I can see the links now.
I have an older version of the Hand-and-a-Half. The newer ones are more lightweight, but I haven't looked at them closely enough to know how sturdy they are, or how sharp they are. The size of the sword is very much like a typical one-handed sword, but with a two-handed grip.
The Bastard Sword is the newer version than the one I have as well. There have been some extensive descriptions of the changes, particularly improving the pommel and grip construction to mitigate a breakage problem they used to have. A useful side-effect is that the balance is much better now too. For the price, the blade is actually very well made in terms of strength and flex, but it's not very sharp as shipped. It's still plenty to fly right through pumpkins (cutting them seems to favor blade mass over sharpness). I'm not sure how well it would handle tatami or pool noodles or anything like that. It's probably fine against water bottles.
