I've seen Kai scissors marketed under both Prym and Janome brands. I only have their ergonomic snips but they're tremendous so I'll consider them next time I'm shopping for scissors.
I love my Gingher 5" Classic Knife Edge scissors. They are so silky smooth and slice through layers of thick fabric with ease. More expensive but hard to resist I think.
I've been very disappointed with Fiskars, however. Their snips were horrible. I'm right handed but they roll and twist in my hand as I press the blades together. I soon replaced them with the Kai. I also bought a pair of Fiskars Amplify 24cm scissors which rapidly became blunt and no longer cut to the end of the blade. I did use them on lycra which I sew regularly and it's really tough on scissors, I know, but I was disappointed nonetheless.
For a great economical scissor I've been really impressed with the
Westcott Titanium Bonded scissors. Mine are still cutting through lycra without trouble 4 years on. The price I see them sold for fluctuates but I paid around the price shown in the link.
