I purchased these knives in 1982 or 83 from a locally owned 'big box store" in Mass. called Lechmere. They were going out of business and had these reduced 75% or so they claimed.
Recently, when buying a carbon K-Sab parer from a local restaurant supply, I mentioned the set and the owner told me he remembered those knives from back then and they were knock-offs (read fakes). The screened markings on the blades are long gone and I cannot remember what they said, aside from Sabatier. There was definitely no "K" prefix.
As you can see, the finger guards and bolsters are cast aluminum with sloppy braises to the blades on some of them. The tang is steel and goes to the end of the handle. The spines are square, not rounded. I believe the handles to be a plastic composite of some sort and a couple of the handles have cracked through on one side or the other at the rivets....across the handle, not lengthwise.
Any idea whether he is correct or not?
