Famous old-school balisong collector Lew Glos has contributed pictures to publications such as Alexandrou & Galiyeva's "The Heart of the Butterfly." His extensive collection includes one of the best of 1980's imports. Some of his images were once viewable on Stanley's old Asian Dragon website which is now defunct. The Asian Dragon archive can be viewed here, although many links may not work: http://web.archive.org/web/20021005132411/asiandragon.hypermart.net/index-ns.htm
He sent me his old collection of prints which I have tried to clean up and digitize using Photoshop to increase clarity and definition. The dates that appear in either the picture title or caption is not the manufacture date of the knife but the date that Lew purchased the knife. As most of these were bought at gun and knife shows, the purchase date does not reflect the manufature date. Enjoy!
