Get an Umnumzaan instead of a Sebenza. It has a thicker blade, thicker handles, a stronger lock and virtually ZERO maintenance due to an internally sealed lubrication system. The washers which keep the blade and handle contact points lubed are grooved and retain the grease and even when used underwater, washed, buried and exposed to all elements making the cleaning intervals a fraction of the Sebenza. The cutlery specific S30V steel is highly impact resistant and has great corrosion resistance as well. It is hard to rust, corrode and oxidize and I have used it in marine environments as well. Mind you, I would wipe it down with freshwater after use to prevent corroding but the knife would see 24+ hours in a saltwater environment before getting rinsed off. It's easy to rinse with an open handle design with no encased areas. If you are using it in marine environments often enough to rust stainless steel, use Tuf-Glide and then you get even more protection. Titanium is not affected by marine environments whatsoever. I've used the Umnumzaan to split 2x4s by batoning (using an object to physically hammer the blade through the wood). Look at my review on the Umnumzaan. I do just a few small around the house chores and yardwork to shows its ease of use and design but I will tell you now that I have done things with this knife that any other folder would have broken if they had been exposed to the same level of heavy use. The Umnumzaan is a pocket fixed blade. If the Umnumzaan cannot handle your tasks, you are doing something wrong.
