of these with hard-rubber padding, so they don't scar the connector.
Use of a vice, without some sort of similar guard, can leave teeth
marks in the connector. You also risk crushing the connector if you
are too overzealous when you close the vice. The only time I used my
vice was when making 50 conductor cables for early SCSI connections
because there was too much force needed to completely compress the
connector on the cable.
