I don't think that exists.
You can give up one side of the handle to a slab of steel or titanium and get something like a spyderco leaf storm, or strider sng.
Or you can have two steel liners, but get g10 handle scales with pillar construction out of a benchmade axis lock knife
Or you can give up on the pillar construction and get a CS Triad lock knife.
A liner lock or frame lock will have to have some form of a steel liner on the lock side, even if its just a partial liner.
An axis lock will also have a steel liner for the bar to ride on.
A friction folder will allow for you to have full g10 handles with no steel liners and pillar construction but you won't have a lock, although there are some pretty trick designs out there that will be even more secure in use than some locking knives.
