For the last little bit I've been pooling resources with JB Knife and Tool to help both companies move toward getting more work out into the hands of customers. Brian and John of JB Knife and Tool are good guys with a great deal of practical experience on the knife making and using sides of things.
For Blade Show this year, we threw some tech at the tomahawks and the result was me building the largest batch of tomahawks I've done so far. The blanks are waterjet cut and hand ground with an angled workrest, as it has been since I started. The grinder has been upgraded to an AmeriBrade and the work rest is the far more adjustable D-D Work Rest, but the basic process is the same.
When it came time to make handles and sheaths, we made use of a tabletop CNC router. The handle slabs were shaped in three stages, with three different tool changes. This meant someone tending the machine and manually changing out the bit and collet, then re-zeroing the router before starting the next stage. It was still quicker and more consistent than the old way, using jigs with table routers. We're looking at a larger CNC router with an automatic tool changer for a future upgrade.
You can see some of the stainless steel tube rivets cut out in the little container at the top of this picture.
Sheaths were molded on forming molds I made a while back using steel layers waterjet cut and assembled to create a three dimensional form, pressed with my big hydraulic forging press. We are working on a design to be machined from one chunk of polymer to be used for vacuum forming the sheath halves. We rigged a temporary fixture for drilling holes and trimming the outside of the sheath halves using the tabletop CNC router. A more permanent holding fixture for trimming the molded sheaths is next up after the vacuum mold.
Even with the older molds and temporary fixture, the results on trimming sheaths was quicker and more consistent than the old method.
In addition to inventory for my own tables at the Blade Show, I made deliveries to a couple of dealers at the show. Here I am loaded down with two different deliveries.

The 'hawks are made from 1/4" 80CrV2 steel, coated with Cerakote, handles are TeroTuf, sheaths are Boltaron.
The techniques used on the tomahawks are in the process of being implemented on my line of mid-tech knives as well. The first batch of knives that will be getting CNC routed handles is being Cerakoted at the moment.
