Answer:
I know a word of letters three. Add two, and fewer there will be!
Hard to catch, easy to hold. Can't be seen, unless it's cold
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
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.
My teeth are sharp, my back is straight, to cut things up it is my fate.
