I definitely have not seen this.
Would be easy enough to CNC, but the fully-vented design is one of the things I like most about the Senenza. I thought the Lochsa was kind of a step backwards in that respect.
As with some of the Strider folders' features, the Lochsa was touted as having enhanced rigidity by virtue of its one-piece frame. Seems a little ill-founded, given that even the Sebenza is going to fail at the blade, not the frame if it is pushed to the breaking point.
