The difference is that the Separating Blade is made from a stainless steel wire that is coated with the same high quality process as all our blades and then has a coupling attached to it which is also coated for protection and smooth action. This blade gives you the ability to open the blade, slide it through, reattach and make internal cuts with no entry point.
