The old Wenger factory at Delemont is still producing knives, but they now carry the Victorinox brand and shield. The Evogrip knives, and others in Victorinox' "Delemont Collection," are produced in the old Wenger factory and are essentially Wenger knives. But the Wenger brand is no longer used.
Economics would suggest that the Delemont knives will continue to be produced so long as they are profitable and do not negatively impact the regular Victorinox lines.
From what I have read, the Victorinox factory is much larger, relatively new, and likely more profitable, than the old Wenger Delemont plant. It is probably only a matter of time until the old Wenger factory is shut down for good.
