The Maxpedition Excelsa is a pretty nice titanium folder with a D2 blade. There is the Lionsteel Sr1a has a D2 blade with an aluminium frame. Just be wary mine came with kind of a jacked up grind. The tip and front was quite obtuse in its edge. I think there are other Lionsteel knives with D2.
As a side note...If you like D2 and are concerned about corrosion resistance maybe you should check out folders made from CTS-XHP. Supposedly it is like D2 in its properties and behaviour, except it is a stainless steel. D2 is only a semi-stainless steel.
