It depends on what you mean by compete. There are knives that can compete by having similar materials, some finishing details, size, country of origin, and price range.
Is there a company that can competitively do the combination of what the Sebenza does with overall quality inside and out, fit, market and physical longevity, and an unmistakably iconic look and feel in operation? No, I don't think there is. You spend some time with other US made peers at that price (and often much higher) to the Sebenza, take then apart every so often, look every detail over, use it for several years. There is something the Sebenza has that there other companies don't. The Sebenza is unique and iconic.
That doesn't mean you are going to like it, though, or that any number of comparable brands won't make you happier.
