Review on Tramontina 80020/005 Diamant Steak Knife, 5-inch, Single Pack by Kristen Jeanguenat

I can't talk about other qualities except that this is a very sharp knife and if it doesn't need sharpening (it still can't be sharpened). If used properly, it should last quite a long time. There are better knives out there, but the sharpness is NOT AT THE PRICE! I bought 12 and have no regrets. You'll break down your dirt (and your fingers) if you're not careful when cleaning. You haven't had knives long enough to judge durability, nor can you judge the quality of a stainless steel blade - plus they should be cleaned after use (abrupt/careful).
