Michael Gettier, yes, the famous Chef Michael Gettier of Antrim 1844, is actually a serious balisong collector. His impressive collection includes some outstanding Bali-Song Customs, Dobruski, Largin, Miller, Erickson, Pabu, Perrin, and others. While the presentation is sparse, the pictures are all top-quality. (By the way, he also has another website where he sells some software he's written for managing production kitchens. It only costs $19. The average home kitchen doesn't need such organization. But, here's the neat part: The software comes with a very extensive collection of Gettier's own original recipes. The recipe list is well worth $19. Click here for more information.)
Dudley "Dropcloth" Dawkins is a major balisong collector. I call him "Dropcloth" since he's famous for using an old painting dropcloth as a background in his pictures. And pictures he's got -- of some really nice balisongs. While he specializes in Bali-Song, Pacific Cutlery, and Benchmade customs, he also shows several Dobruskis and a few other customs too. It's quite a collection.
Please note that a lot of people like to put picutres of their balisong knives up on various photosharing sites. But, the problem is that these sites tend to sort of come and go. The links here to to display sites that have proven to be long-term stable.
