I have the same "Engineer" pair as member dede2897234 and echo his satisfaction of the item. They are a convenient little work horse. Find myself using them on a regular basis for cutting plastic, cardboard, clothing, nylon, rubber and of course paper. Haven't tried them on leather yet. I have however used them to open boxes with their advertised tool feature.
They are bit expensive, but they are great at handling the quick power cuts you can't get from most scissors. They are a little cumbersome on the longer cardboard type cuts, because of their shorter cutting blades and compact style, but really shine on short yardage situations at the line of scrimmage...
