We have had our knives for a few weeks now and they have transformed the way we cook. OMG, I never knew a sharpened knife  could make such a difference. Cutting meats is so much easier. We now are buying bulk and easily cutting different cuts of meats with our ninja knives. They are awesome and we are no longer using our cutco knives. The three adults in my home prefer by far the ninja knives over all the others we have. They are just amazing!!!
