NEPS Epee Point Screws make being an aging epeeist a little less burdensome. I remember being at a tournament with an older guy who needed help putting a screw in his point. We worked and worked until I asked lil Pete to take a look. There was no slot on the screw but neither of us could see it. You can put in a NEPS screw just by feel very nice setup. If they have a bit of sense they'll expand to glasses screws etc...
