I notice d that too, they make a lot of fake blades now, cheap thin sheet steel with the central ridge stamped in to a left/right half, edges welded then ground a bit. Blade appears thick but is hollow. If the hand grip is resin, the 'silver' may be plated.
I had one more than twenty years since that someone had attempted to sharpen on a wheel, resulting in the partial separation of the two halves.
