We sharpen all the Elites for 3 Rivers. We shave or rubberband test every blade before they leave the shop too. The Elites are carbon steel and even though we oil them, if they sit on the shelf for a couple of months, there may be a slight corrosion of the cutting edge, or sometimes the oil will dry and create something like a thin coat of varnish over the bevels and cutting edges. Try this: Get a long piece (16-24") of plain brown corrugated cardboard, and just strop the heads (pull them backwards) about 15 passes per side over the cardboard. I'd be very surprised if they don't come right back to shaving sharp from just stropping them. Thanks,
