Answer:
We are five little objects of an everyday sort. You will find us all in a tennis court.
Talks like this, a green wise man does. Guess my clue, you will.
With sharp edged wit and pointed poise. It can settle disputes without making a noise.
My first is in wield, sever bones and marrow. My second is in blade, forged in cold steel. My third is in arbalest, and also in arrows. My fourth is in power, plunged through a shield. My fifth is in honor, and also in vows My last will put an end to it all.
We are few to the wise; We are abundant to the drunken; We can calm the beast and are precious to the child; We can devour the heart, without piercing the skin
People take me on walks and I run and have fun. What am I?
