Professional SIGNI PSA Diamond Precision Lapping Microfinishing Film 5 inch (3 Micron, 5 Pack) - High Performance Polishing Sheets for Optimal Finishing Results

Signi lapping film contains carefully graded aluminum oxide particles that are electrostatically coated onto a high strength polyester film backing. This fast cutting, water resistant abrasive provides precise, consistent, close tolerance finishes, and are available in a wide range of precise micron grades to meet any sharpening or polishing need. They can be affixed to a hard flat surface (usually 1/4 inch glass) and used to get a scary sharp edge on wood chisels or plane irons. They can be wrapped around contoured sticks and used to sharpen carving tools. They can put a wicked sharp edge on all kinds of knives. They can also be used to put a fine polish on jewelry or gem stones. These are PSA (Pressure Sensitive Adhesive) backed. They have a 3 mil high-strength polyester film backing which is less likely to tear than traditional wet or dry sandpaper.
