The wire shaving process produces fibers that have geometric cross sections. The result is that each metal wool fiber has several long, sharp cutting edges. Unlike sandpaper and other grit-based abrasives that scratch away material with sharp points, metal wool fibers perform like thousands of microscopic scrapers or planes on a surface. The result is a smoother surface after sanding and a better result after finishing. Fine metal wools are even used to clean glass and polish fine wood articles.; ; Brand Name: Rhodes American Steel Wool Grade: 00 Grade Grit Type: Very Fine Product Type: Steel Wool Pad Number in Package: 12 pk Width: 4 in.
