A.G. Russell's original K-87, all SS, One Handed Knife. A more compact, strong, lightweight & useful general purpose, everyday folder, I cannot conceive. Not to mention a design that was/is a work of art & engineering achievement. The flat stainless side panels were perfect for engraving names and commemorative events, thus making them great gifts for important occasions. All wrapped up in a reasonable price. There was also a small pen knife sized variant. There are later versions in zytel frames and even SS models with scales and larger levers. But, IMO, they do not compare to the originals. For the life of me I do not understand why it was discontinued.
