Maybe, maybe not. Reputable, trained sharpeners will often have bad days, just like stylists and deserve the courtesy of the opportunity to fix their work. However, before you call him back, take a close look at your shears. Open the shears and look at the inside of the blades. A correctly sharpened Japanese type shear will have a shiny line called a rideline or hone line along the cutting edge of the shears. If the shears have a shiny line up the back side of the blade, on the side that does not cut, your sharpener most likely doesn’t know what he is doing.
I was just sent one of our Bonika Shears which was sharpened incorrectly in another state. These shears have a rideline on both the cutting edge and the back of the blade. He seemed to have taken the shears apart to sharpen them, (which is the correct way to sharpen these shears) but he put the pressure in the wrong area of the blade and changed the plane of the surface. I am unable to fix these. Bad sharpening is not covered under our LifeTime Warranty. Their sharpener did not understand the geometry of the shear blade and changed the dynamics of the cutting edge. If the stylist had sent these back to their sharpener to resharpen, they would have been even worse.
Be cautious when you give your shears to a scissor sharpener. One bad sharpening can take away your entire investment.
Note the shiny line on the front and back side of the blade. This is due to improper sharpening.
