Why do pepole think that staneless is good blade matierial?

Question

It is not. A sword made from stainless wont rust. But it wont hold an edge either. A solid Iron core blade with a welded steel edge can slice right through it. (Yes fellow Mythbuster fans, it is possible. I have done it three times.) After a time of using it, the blade will warp. So why do pepole think that an alloy for Cooking Equipment, is also good for a weapon?

Answer 1

 I use stainless because I dont like to take time to maintain my equipment.
