Well, I have no experience with a Custom Exkelibur (smaller) or the LEXK (larger), but I do own the Boker versions of these knives and they are excellent. I can only imagine that the actual custom work from Burger are even better. I really like the look, the feel, and the opening method on these knives. The blade shape is great for general utility and the handles are quite comfortable. These knives are very sheeple friendly. The satin finish on these look really good. I would recommend checking out Boker's offering before jumping into the custom. I've heard from folks that own both that the look and feel are identical, but the build and materials are what set them apart.
I do have experience with the AG Russell Acies as I have owned one since they were first released. I love everything about the knife. The one exception I had was the clip when I first received it. The extreme shininess of it was just too much. I hit it with a blowtorch real quick and dulled the shine. I would get into all I love about this knife, but I'll keep it simple and let you know that their are a few threads that detail this knife quite extensively. I will say that I've carried and used the knife, sharpened and stropped it, taken it apart, cleaned it, and put it back together a dozen times. The blade shape is damn near perfect, the angled thumbstuds are my favorite, it opens up and closes so smoothly, and I've never had an issue with lockup. It doesn't CLACK open like alot of framelocks do, but I have no bladeplay and I have no issues with the lockbar.
A bit more about the Bokers...
I know that comparing the Boker and the Burger models isn't very fair, but I believe that the sizes and profiles are the same. I believe that the large Boker is the same size as the LEXK and that the small Boker is the same size as the regular EXK. If you look at the picture with just the Bokers you can see that the area where you flip the knife opens is different on the large and the small. On the large the steel extends out a bit farther making the flipping action very easy and smooth. I can wrap my forefinger around the top of the knife and flip the blade open easily. On the smaller model I can't get the knife to flip open with my forefinger. I have to use my thumb to get the small one open. I am not 100% sure if this difference is the same on the Burger models. The picture of the backs of the knives are where there are some differences in the Boker models. There is the Exskelibur which has the closed back, red fiber liner, and single blue ano Ti liner with smooth G-10 scales. This is on the larger model and is much slimmer. The Exskelimoor has double blue Ti ano liners, blue Ti standoffs, and Bog Oak scales. The double Ti liners with the Bog Oak scales make for a thicker handle. Again, I have no idea if the difference in these Boker models are the same differences in the Burger models.
Anyway, let's get to some pictures. I know that these aren't the best pics, but I don't have a whole lot of light in the backyard right now.
