I have to admit I almost called on one of those knife show ads. But then I snapped to. “Okay, at $6 a knife that’s a good deal. But what will I do with 36 of them!?”
They’re horrible knives that are cheaply made and are dangerous quite often.
If you’re interested in cooking, invest in something like a Wusthof. I worked in professional kitchens for 15 years and have one chef’s knife that I bought in 1989 that is every bit as good as it was the day I bought it.
