Congratulations Aaron! What improvements do you have in mind for your next batch? I'm still waiting to see if you can figure out how to machine the Corbies flush or rough out the entire bevel on the CNC
Edit: I also have to say I was super impressed with your thermoforming jig for the sheaths!
Haha, thanks Neil! That jig would have been even more impressive if it had worked
For the next batch the main improvement will simply be that I have the process mostly ironed out now, I should get to cruise through it with much less stop-and-start and hopefully put some money on my much-abused credit card

Probably the only change I will make is to build a jig for sharpening wet on the grinder.
The batch after that I'll be looking at getting a second kiln with inert gas plumbing, and an oven specifically for the Cerakote, those two should speed things up significantly in their respective steps! Once the kiln, sharpening setup and Cerkote oven are sorted then that will leave the sheaths as the slowest and least consistent step...
There are 5 main areas that I want to address going forward:
1) Better materials and process for the sheaths. Whether I have those injection molded elsewhere or make them in-house I am not sure, but I want to improve that part of the process. Fibre reinforced nylon or similar is likely the perfect material, but that's not something I can do in house unfortunately so I'll have to investigate some options!
2) Another round of steel testing to decide if I continue using A2. I've been very happy with how it's performing, but now that I'm better at heat-treat and so on I want to test CPM154, CPM4V, CPM3V and a few others against A2 to see which has the best properties for my knives. Very high hardness with high toughness is the goal. I've been immensely happy with how high-hardness A2 performs, that level of performance with even greater toughness would be amazing! I'd also like to experiment with differential tempering to see if it can add useful abuse resistance to my blades.
3) Handle attachment method. As you alluded to, the step of having to hand-shape the corbies/handle is an opportunity for inconsistency and error! I would like to look at other attachment methods or machining techniques to eliminate that step. Preferably I would like the overall appearance to remain unchanged and I would like to improve strength at the same time which is a tricky proposition!
4) Test new coatings! I've been talking to a company about several PVD coatings that might work well for my knives. The main candidate right now is a dual layer coating of Chromium Nitride for wear/corrosion resistance with a top layer of a black coating called WCC for appearance. I plan to test this along with several other coatings like DLC and possibly TiCN (depending on steel) against Cerakote to decide what I'll use going forward. Cerakote definitely has exactly the appearance I want, and is very corrosion resistant but I need to see what else is out there!
5) Larger shop with dedicated production setups and tooling... Right now my production/prototyping machinery and tooling are one and the same which means that I'm either prototyping or I'm producing, can't really do both at once. I would like to setup a full set of production machinery so I can really dedicate tools to specific tasks and get everything streamlined. This will include buying a larger machining center with greater tool capacity so I can machine blades and handles at the same time.
At this point I may also look into bring on another person to work with me in the shop. I'm still not sure about this, and I definitely never want to go past the stage of 2-3 people (including me) in the shop, but I think it might be a good thing for my discipline and motivation as well as productivity. Finding the right person will of course be a challenge as I want someone that's going to really add to my capabilities and not just be a button pusher... We'll see, that particular thought is very speculative at the moment!
So that's pretty much the roadmap for the next 6-12 months! The goal for the next 3 months or so is simply to get a bunch of really good knives out to customers who have been patiently waiting, and to get myself into a less precarious financial situation!
