I haven't ever seen that Laziza packet over here. Is it any good?
The Wiltshire Stay Sharp knives have been around over here for decades. I remember the first one we had in the 1970s. They were first released in 1969 and there would have been very few household kitchens that didnt have at least one. They do stay very sharp but due to repeated sharpening every time they are put into, and removed from the scabbard, they reduce in blade width very gradually over time. This eventually causes it to no longer make contact with the sharpening mechanism. That set would have cost Au $56 (rrp) today but could probably get it cheaper on special. If you keep them away from the scabbard and only use it occasionally, you'll get more than 10 years out of them. There are some of the originals still around after 50 years.
That said, the riveted on handle will be the downfall. Prior to 2020 they always had high density moulded black plastic (nylon?) handles that never let go.
