I am guessing that the Dominator will actually be stronger than a Madd Maxx. The smaller frame is stiffer due to the extra stand-off screw near the pivot, and has some slightly different lock geometry.
However, repeated opening and closing of an assisted opening knife like the Dominator will certainly accelerate wear on the stop pins and locking bar.
One thing about Darrel is that he is always refining his designs, especially in regard to edge geometry and lock performance.
I am currently abusing a Dominator, I will report back.
