The bulldog pattern is a traditional slipjoint that's usually about 5" - 5 1/2" closed. This pattern isn't very common. However, Rough Rider brand offers it in several different scale materials. They also offer a large coke bottle pattern slipjoint that's about the same size.
I think the large Okapi slipjoint is still available, and it's about 5 1/2" closed. This is a much cruder knife than most, but makes a fine user.
