Whatever you do, don't try and re-sharpen any modern blades ... the stainless steel with titanium/chrome coatings may leave behind deposits on your gadget that will ruin it forever.
If you can figure out when your sharpener was made, try it out on blades from that era ... or better yet, blades from at least a decade before, to be on the safe side.
