Want a sword you can carry around without risking arrest? Get a wooden one. If you are interested in training anywhere but your own backyard, you need something that won't trigger LEO interest, and in a lot of places it is actually illegal to carry a sharp sword. It can be in your trunk, or you can be going directly to your training hall or place of exposition or returning directly home--stop for a burger and you are looking for trouble. Seriously, check your local laws; it can be legally safer to open carry an AR-15 than sharpened steel thanks to some dumb*** who wanted to get his name on a law. Colleges in particular are gray areas and may have campus rules worth knowing...Never again will I train with a whip chain in a an open field.
Hung Gar uses a lot of weapons but always starts with the basic 4. It is recommended to have "3 tiers" of training weapon. First one is always wood, second is blunt, third is a sharp that is heavier than the weapon you would actually use. Wood is a great material, and more forgiving when you nick yourself or your surroundings. A friend training with his blunt bent his tip hitting a floor, and since it was a blunt he could just straighten it with a hammer--pity he didn't notice it was a waffle face though. If you don't like what is available, you can make your own; I like purpleheart for heft and density, but a curved ax handle could quite easily become a saber. For entry level metal weapons, the brand you probably want is Longquan. For about $80 you can get a dao that handles like a weapon should and will survive training. Avoid weapons that have Wu Shu, Wu Su or damn near anything with Wu in the name. "Modern" is also code for "super light, flashy, tinfoil blade." Look for a "traditional," "spring steel," or "combat steel" sword to get a blade that is realistically weighted and won't flop like a politician on debate day. Training weapons are meant to be disposable because you will be learning what not to do, usually the hard way.
