This tool is a bit over ten years old. As you noted earlier, Gerber is a division of Fiskars. After bringing out a small prototype run of their new "Multi Plier" to compete with the Leatherman PST, Gerber brought out this model in the early 1990's. At some point, they produced a limited number of tools with the Fiskars logo on them. And an even smaller quantity of tools were stamped Fiskars and given a black oxide finish. The stainless steel finished/Gerber logo tools from this era are still available by the dozens, but I've only seen a couple black Fiskars like yours.
