After training a weapons form for a number years it is perhaps useful to consider buying a better sword.
A well-made sword will cost quite a lot of money but is entirely different to a cheaper one.
Many tai chi chuan students can perform elaborate routines using telescopic swords or wushu weapons, but may not fare too well with a 2lb sword.
To handle a sword of the correct weight, your body must compensate by balancing the weapon.
This demands an increase in skill.
