Nope. All made in the same Japanese factory as always.i've got a feeling that whereas hooks like carbon chubs were made in Japan,i'm just guessing,but i've got a feeling they are being made in China,like everything else and wonder whether the accuracy is as good limits wise.
The shank length on Carbon Chub is a bit longer than Wide Gape but the actual gapes are not vastly different (about 2.9mm for Carbon Chub and 3.0mm for Wide Gape in an 18 but bigger difference in a 20). To the eye Wide Gape look wide gape because the shanks are a bit shorter and deliberately so. I prefer the way bait sits on the Wide Gape as Carbon Chub were/are crystal bend with a rather acute angle at the base of the point and swept up radically to the shank. But that's personal preference. That said I still use 22's in 'older' hooks simply because, to me, they are 'proper' 22's. Wide Gape Match being the exception.
