Pro-player Effren Reyes has his hand in and fully endorses the 3^rd Generation It’s George Tip Tool! The key features that make this tool stand apart from the original are the two concave sides.  One side is a coarse grit for regular tips and the other side is a super fine grit for layered tips.  Included is a stainless steel tip pick on the tip of the tool. Crushed carbide mixed with copper slurry is heat welded onto the surface of the tool so there is no glue or epoxy that will start to flake off years after use. The tool also has a fancy hole for a keychain ring so you can hook this right to the zipper of your case or your keys.
