Collection of unusual modern studio ceramics

Was lucky enough to come by an interesting collection of modern looking studio ceramics at Peterborough yesterday. These ones appear to be to by the same artist, some elongate 'scabbards' and other items with some interesting glaze and texture effects. There are no clear potters marks as such, although an 'eye' mark (last picture) does appear on a couple of the pieces. Any ideas pot experts? Thanks.

They look like they're copying the patina on copper and bronze objects. May be from Greece, copies sold in museum shops.
