[Witcher] Why bother carrying steel weaponry?

Ok, witchers carry a silver sword for monsters and a steel one for humans. Why not just carry the silver one and spare the excess weight?



I get that silver is expensive and not as strong as steel so you probably don't want to be bashing it against armour or other weapons and whatever, but when your powers include mind control, telekinesis, pyrokinesis, a magic shield and traps, super speed, super strength and super reflexes, surely your fights against humans are going to be so one sided that there isn't going to be much dueling involved anyway?

The silver sword he carries, along with being more fragile, doesn’t hold an edge as well as the steel one.  Think of the steel sword as his every day, chopping whatever need to be chopped sword.  Humans, animals, vines, whatever - steel sword.   

It’s only when things have taken a dramatic turn for the horrendous that he’ll risk using the expensive, rare, enchanted and softer metal sword.  

Lastly, the additional weight is inconsequential due to his heightened Witcher’ie abilities.
