As your strength increases and you become familiar with the form, explore a
heavier weapon.
If you can find an unsharpened blade, this is perhaps the wiser
purchase initially.
A genuine sword weighs between 1-2lbs; which is quite heavy when held in front
of you.
Compensating for the weight will require you to connect throughout your body.
The blade makes it necessary to be both relaxed, alert and precise; you cannot
afford to be cut.
A good sword can cost quite a lot of money and needs to be handled
skilfully and maintained carefully.
The balance of a quality sword is entirely different from a cheaper
weapon.
