The pointy jaws of this cutter are flat on one side, V-shaped on the other. When you cut wire with this tool, you'll end up with one wire piece that has a flat, or flush cut, and another that's angled. Again, when aiming for a professional look, a flush wire cut is so much nicer to look at (and to wear) than a mangled angled one.
This is a tool that you will want a nice fine point on. The smaller and finer the cutters, the closer you can get into your work for a nice neat cut. However, you can ruin them on heavy gauge wire. Always buy yourself one fine flush cutter and one heavier duty cutter.
