"J-Hooking", "The Gillette Slide", and "Blade buffing." Has anyone on the board ever actually employed any of these techniques? If so, were they effective, or did you just wind up cutting yourself and/or giving yourself razor burn? I am thinking about trying the "Blade buffing" technique to get the pesky patches of hair, which remain in the crevice where my jawline/chin meets my neck, but I am kind of scared that I might wind up ripping my skin to shreds. So, has anyone ever followed Mantic's lead by going the "Advanced" route while shaving, or no?
