I wouldn't think to judge anyone's taste, phillistine though they may be, but to say that all Spyders look alike because they share the hole? Really?
The Lum Chinese looks like the Lum tanto how? And how are they indistinguishable from the Wegner? I would venture to say that most any of us could discern the Chinook from, say, the Gunting. There are Spyders with the "hump", and Spyders without. Spyders with steel, G-10, Ti, carbon fiber, and plastic handles. They come in a variety of colors, and some have shell inlays. There are any number of different blade shapes, steels, and edge configurations. There are little blades, big blades, and everything in between. Spyders for work, dress, or combat, and all specifically conceived and executed for their purpose.
If you don't like anything in the Spyder line, that's no big deal. Taste is personal, and everyone is entitled to theirs. But your premise is like saying that all Mercedes look alike because they share the same emblem on the hood. If you can't see the differences, well, it takes all types I guess.
