I'm surprised we don't see more emphasis on waterjet cutting for skeletonizing handles.
Profiles, you can do with a bandsaw. Waterjet cutting saves you the time. Holes, you do with a drill press (and in fact, even after they're water-cut, you still have to drill them, so the benefit is in consistent layout, not in saving any time).
But what's extraordinarily impractical, prohibitively time-consuming, in knife shops without a mill is skeletonized handles. We go through all the trouble of tapering tangs for weight, but aren't excited about getting blanks cut with the tang already hollow? It's frickin sweet! And it's every bit as easy to order them that way as it is to order them solid.
In my book, that brand new capability is probably the coolest feature of all. :thumbup:
