Serrated Scissors and Shears Facts
Sewers and Quilters
I used to have a pair of Ginger G-8Z serrated bladed scissors that I loved...well, they got dull and then I discovered KAI® Scissors. THEN... Clover came out with some serrated bladed scissors and some national instructors started raving about them. Sew....I inquired of more details by the 'Scissors Man/expert' that I am acquainted with...and here is what he says. Take it or leave it - I'm just sharing facts.

Londa asks David: "I note with interest the new Modified serrated edges available on some of the Kai Scissors...I need the scoop - the details.
Are you doing this yourself at your supply/factory? "
David Answers: "We do the corrugations in house, they are for hard to cut materials like Kevlar. Not any value to standard fabrics, if you are selling to someone who has to cut Kevlar threads, or other aramid fabrics then the modified scissors would be a good fit. They do not feel as good as they have to be over curved and tighter to cut these materials."
Londa asks: "What does it add?"
David Answers: "For customers that don’t need to hold the aramid fibers in place nothing, a bullet proof vest works because of the layers building up and stopping the bullet when they try to shoot through these layers. You can mention that corrugations – serrations are available but not preferable for most fabric applications.
Londa comments: "Thanks for your reply. I believe you completely, but I can assure you, the women are convinced - I think from the few Clover scissors and the one Gingher, that serrations help 'hold' the fabric - especially slippery ones. I'd LOVE a technical explanation to share with them....."
David Answers: "When we don’t polish the bottom blade it has micro serrations that can be seen with an eye loop. This micro serration keeps slippery material from slipping while cutting but has the added advantage that the edge holds up longer then a serration that is visible to the eye. The visible serration chews while it opens and closes against the upper blade and causes it to dull quicker.This is true info, the bottom blade that is sharpen on our sharpener leaves a micro serration.
Londa asks: "That helps - but I'd need to know if a regular sharpener guy - who seems trained, looks like he knows what he is doing - would be leaving the same micro serration."
David answers: " A professional sharpener should ask the customer how they intend to use the scissors, slide cut or open and close on slippery material. If they don’t want to slide cut then he would sharpen both blades, leaving the find micro serration and then polish the finger – upper blade to allow it to cut with little pressure. If they are going to slide cut then the sharpener should polish both blades as this allows the scissors to pass through the material with out catching and cuts it like two knives are running through the fabric."
