The knives are solid, heavy, sharp, the design is super, the durability is definitely the highest. Happy as an elephant. Don't waste money on them for a second. Knives in the house live a very long time if they are of high quality, like these. 100-500% worth the purchase. And yes, the knives really cut paper - at least into thin strips 2-3 mm wide, at least into thick slices. This is the first time in my practice such beautiful knives. GET IT, YOU WON'T REGRET.
