Hi Tom. As mentioned, what you are planning on slicing does make a difference. For things like cardboard and shrink wrap, my first choice would probably a serrated VG-10 delica. Slicing through something is often the result of the ratio of the width and thickness of the blade. The thinner wider flat ground kitchen knives are a good example of a geometry made for slicing.
If you don't like sharpening, then serrations do stay sharper considerably longer.
If you are using a Military now, what are you using to sharpen? I keep my mil at 30 degrees and cardboard is easy. I use a Triangle to maintain the edge.
The Chinese folder is also an excellent slicer.
