I have bought these knives there are 1 year and a half and they don 'have not lost their edge. They replaced our laguioles brilliantly, for the use they prove handy for cooking at home, eg peel and cut an onion, cut tomatoes, cut the bread and of course the steak. Pay attention anyway because they cut hard, take some precautions: Do not allow children; In the dish rack always store the tip downwards; Never enter a knife with the edge; When you wash the dishes made them one by one because we must not plunge all at the same time you may be injured by retrieving, also imagine someone who does the dishes behind you and who does not know that these knives are basically, that is what happened to my mother so watch your fingers!
