I think in this case we should agree to differ as I have a selection of both Fatip OCs and half DE Blade Razors. It may be a case of YMMV!Blade rigidity comes from the SE blades themselves (GEM or AC style) which are significantly thicker. These are still foil thin DE blades in the Eco razor. Get a Fatip OC and shave with just one side, done. Rigidly held DE blade.
