I think the 511 will make you a GREAT all around user/camp chores blade. It should also make a fairly good skinner with the belly it displays. Probably better than the S5 or Rodent solution or the wardog. And YUP, a person doesn't really need flash, but if you can get it with functionality for a descent price it's nice!
Now all you gotta do is settle on a larger blade and then a small one. Personally I like the Swamp Warden for a companion blade as it is a Skelly blade so you could piggyback it with a larger blade so they are always together. And it will work fine for most things that you would use a 3 inch blade for. The Scrapivore is smaller and would work well on much smaller game though, and possible even better on snakes because of it's size.
Ok The 511.....Check
Large blade....Still checking
Small blade....Swamp warden ( I would still get a Scrapivore and use it as a neck knife so you would always have one on you).
Nice to have.....ScrapMuk as a GREAT skinner mainly, but as I said those that have it LOVE it for all kinds of work.
** If you can do it, order a Scrapivore with your 511 and have them shipped together.
