This is my favorite Swiss Army model period . I love the Alox ,not plastic sides , perfect size for hand . Not too heavy.The Farmer is a great knife . The saw shreds through wood,plastic ,rope etc. Of course the blade doesn't rust at all and the reamer is very handy . Can opener works fine and bottle top opener also. A very classy but practical Swiss Army knife
