I bought them for very thick wire (copper ground wire #4) and they are not as easy to cut as NWS Fantastico Plus (see review on this). I'm sorting through my wire cutters and these AND NWS are in one pile. Knipex requires more effort and repositioning to make a full cut, but my experience with Knipex is that when NWS cutters are dented and unusable, these cutters cut perfectly and consistently. a daily cut but will probably last forever, especially on steel wire.
