Does Samurai Shark Really Work?

With the Samurai Shark one can save money, they claim, that would otherwise go to having to buy replacement cutlery, garden or hunting tools.  This is because the Samurai Shark can sharpen knives, scissors, garden shears, hunting knives, tools and more.  Even serrated edges are easy, they claim, for the Samurai Shark, something that no other sharpening tool could do before.  The Samurai Shark has tungsten-carbide sharpening blades which the say gives it its power.  This is the ultimate, home smart tool to keep handy in the garage or in the house, they say.  Kitchen knives are naturally burdened with a tendency to get dull, what with their constant exposure to plates, dishes, counters, and cutting boards.  The Samurai Shark is for this reason, they say, an important additional kitchen and garden appliance.
