Overview
This Buttonlock Auto from Robert Sidelinger was designed to be quiet rather than snap your hand back. Yet, the action is positive. This knife was his signature knife. The blade has a hand rub satin finished dagger ground blade with false top edge. Has a stainless steel frame with mother of pearl inlays. The engraving is by "JD". (Please let us know if you know who JD is) Has a couple very light scratches, otherwise excellent condition.
Robert said when he was designing it, he thought the loud noise other knives made when opened defeated the stealth purpose and so he came up with something that still had the same power, with less noise.
