Still looking for more indepth information on fighting knives, but from my knowledge, I really like the design on the Claymore the best. The handles look like they would be sturdy if they were constructed correctly, and I like the blade shape. Looks very capable, I would use it as a survival knife or camp knife. Depending on the materials used, I think it would serve any purpose, and if you made it, it would be the flagship of your company, except for the blue scales. Maybe either black scales, or wooden scales.
As for the Rodent, good neck knife, if that's what you want for it, looks durable, the choil looks too deep, but I'm not holding it in my hands. I would lose the embellishments, and go with a darker colored handle. Maybe good for an EDC fixed blade.
I see the Gator as a big hunting knife, no real value in skinning, but could be a good camp/hunter knife. I'd like to see a longer guard, but I think it looks pretty much okay. Would I use it? Would probably be too big for me, but I still like the design.
I really like the Jungle Explorer, but the handle looks way too thin near the blade, and looks like it will break if used for anything other than cutting string. I would go darker on the handle color, and would keep the basic blade design.
Now, keep in mind that I am pretty much new to the in depth world of knives, so my ideas may be wrong. But, I have learned a lot here, and my ideas may be more right than I give myself credit. The knives mentioned above have good design, slight variations from designs that are established and work, and have a lot of potential IMHO if you get them made. Good luck.
