A knife is just at tool. As any other tool it does have its limitations. Id personally stack 2 moras in each bucket. Then you can get some real tools, axe, prybar, pliers, screwdrivers etc. If you dont intend to carry the bucket around that is. Real tools are always better than the compromise of a multitool. If you have the posibility. If not and a multitool is all you have that is better than the whole tool shed left at home.

I live in Sweden and the moras are dirt chap here a few $ a pice. So I can always get a bunch of knifes just in case.
