    The steel vs titanium debate usually starts with a simple assumption: titanium must be better because it’s lighter and sounds more advanced. That assumption costs people money all the time. Both materials are strong. Both are proven. And both are regularly over- or under-specified because someone focused on a headline property instead of how the […]
