Victorinox is the best. Wenger was a competitor I think, and now I believe they are owned by Victorinox. Kind of like Gransfors Bruks and Wetterlings axes, slightly different styles and models. I'm not sure what the stainless steel is but I've put it through a lot of work some days and have no issue with edge retention or blade play. I actually find the ones with more tools to be more comfortable, but when I first started checking them out I wanted a single blade, so I bought a Huntsman and a Sentry. Took the Sentry back.
