Wow, not a Sebbie in the crowd so far.
Have used a Lg Sebbie for 3 years now, offshore work in salt water environ, used almost daily for prying/gouging/cutting of everything. It looks a bit worse for wear, but is still solid lockup, no play and no pitting. Even survived India's Paradip port several times, which has acidic coal dust in the air without pitting.
Second work knife, mostly used at home is a Snody Explorer. Again slightly worse for wear now, but has stood up to every thing, and done everything with it, without damage.
Neither comes under the heading of "can loose it without crying" but at least the Sebbie can be replaced easily.
