For Serious Minded Stylist. Please read the following in the spirit in which it's intended! Do the Research and make your own conclusions. Less than 5% of all scissors WORLDWIDE are sharpened correctly. Simply put, 95% of all stylists WORLDWIDE should be entitled to new replacement shears or full refunds after only the first sharpening. If you think this is the slightest exaggeration, simply inspect every scissor in your salon immediately after sharpening by comparing the edges to the blades on a new shear...GAME OVER! Stop rewarding your sharpeners with CASH to practice on your shears. PLEASE take your sharpeners to task, especially SHEAR INTEGRITY. PLEASE hold SHEAR INTEGRITY to the Highest Standards. Before handing your shears off to a sharpener or unproven vendor, ALL stylist WORLDWIDE Must take before and after photos or video and shade in the most Telling part of blades of scissors being serviced. Using a colored marker shade in the pivot area by the screw and make sure only the ink is removed and not any visible or excessive metal. This is especially critical for thinners and dry cutting blades with the more complex geometry that too often come back ruined and deformed! NEVER let it be said that SHEAR INTEGRITY removes too much critical metal from your shears!
