A friend so kindly

passed my name on to one of her friends who sells Cutco knives. She did tell her that I'm probably not going to buy anything, but I guess they get paid per demo as well.
The friend originally said that she thought her friend sold Rada knives, so I checked out their website, as this was the first I'd heard of them. I'd be more inclined to purchase a Rada knife, I think, than a Cutco one, but really, we're quite happy with our collection of Henckels and Wusthof knives.
Does anyone have any experience with Rada or Cutco? Can anyone give me any reason I should really consider buying a Cutco knife or two?
