I own several pairs of Kai scissors, they're my absolute favorite, my second favorite is a pair of Karen Kay Buckley scissors.
Both brands are micro-serrated, which means the blades grab the fabric and don't let it slip as they cut.
The Kai handles are super comfortable.
Kai has a free sharpening program that can't be beat. You pay the cost of postage, they sharpen for free. Last time, I sent 4 pairs in, one of which had a bent tip because I dropped it. They replaced that pair with a brand new pair at no charge.
Kai also has customer service that can't be beat. A few years ago, someone here on the board was looking for a pair of specialty scissors, I *think* they were the duckbill applique pair, but in a left-hand version, she couldn't find a pair anywhere. We suggested she contact Kai. They made a pair for her, she was super happy.
