I have ground side cutters and end cutters (nips) so that they will produce a flush cut in laminates in the places a router can't reach. These cutters are no longer able to be used on anything metal for sure but work better than the fastcap product for my needs. I have all the fastcap flush cutters and only use them for cutting brads, staples, nails, and they seem to handle it ok being that they are only used once in a while. I don't know how long they would last in heavy use, but they have cut many brads for me without showing any damage.
