Pure stainless would be near worthless but depending on the alloy it can be very tuff and strong. Take knife blade steel for example so many grades and alloys with various properties. Then theres stainless steel spring steel thats got a fairly high carbon content. Strong tuff and well springy. Pure unhardened stainless is soft and will bend if you look at it wrong pure stainless thats been hardened is very brittle (often called surgical steel as its used in scaple blades) Even this stainless isnt 100% pure and has some carbon added. This is probably some alloy that will be strong light and will be able to flex a fair bit with out cracking or breaking.
