SR101 AKA 52100 ball bearing steel is a high quality fine grain carbon alloy steel with excellent performance values. Fairly easy to sharpen and best sharpened with sandpaper, water stones, or oil stones. Capable of extreme mirror polished edge finishes and straight razor like sharpness it easily makes for some of the sharpest edges I've created. Stropping is a final finishing step or a touch-up for a slightly dulled edge, if the edge feels dull, you can see flat/shiny spots, or visible deformations, stropping will not do much.
Sandpaper or a norton stone would be a good choice for your sharpening needs.
