Valet Auto Strops and Auto Strops can be excellent shaving razors. Some (early models)easily take an SE blade with the spine removed and provide an excellent shave. A model C will comfortably accept a regular old Ted Pella with the spine off and provide a wonderful shave.
These modern blades however are coated and will damage your strops - they are quite hard on the leather surface and do not really sharpen as much as dull.
Try using one and you will find it rather enjoyable.
