Just don't let the steel scratch the copper (or other metal) of the connector and damage it.
Cable TV guys found out, long ago, that a burr on the edge of dissimilar metals will cause a diode-effect, and increase inter-modulation distortions.
They even use a special tool to smooth the edges of the center conductor in the big semi-flex cables.
For RG-6/U and similar, just use a very good "flush-cutter". I also run my finger over the end, or wipe it across my jeans or shirtsleeve, to see if there's a jagged edge.
