The 511 is just okay for me, the handle worked well for me but didn't care for the blade as a whole. I had one of the Military Overruns with the full flat grind, which had a very nice full flat grind which made for one of the sharpest edges I've seen on a Bussekin blade. But as Elof, mentioned the balance was just really bad for me. The 511 should work well as a camp/hunting/bushcraft knife, but I'd actually go a different route for myself....
I would either go with something larger or smaller personally, reason being that a 5" blade like the 511 will never be a good at chopping, splitting and such. It is also too large to excel at the smaller knife stuff like carving, skinning, and such. I've yet to find a 5" knife that I was satisfied with and I've had quite a few.....
-M/O 511
-Custom Shop RMD
-War Dog
-Scrapper 5 SE
-M/O HG-55
In my opinion these are some of the best 5" blades the kin has produced, but I've ended up parting with all of them as they are just too awkward for the small stuff and not up to the big knife stuff.
My recommendation would be either go for something in the 6-8" range if it will be a one knife scenario, OR a large knife (9.5" +) paired with a small knife (3.5" to 4.5") if you can afford them.
In the 6-8" range, I like the the Rodent 6, Ratmandeux LE, Ratmandu Prototype and 711.
For a large knife I like the 911, Rodent 9, M9 and 1311.
For smaller kin, my preferences are for the 311, 411, Howling Rat LM and Rodent 4.
