I am new to this forum. I have a collection of knives that I have purchased over the years through onsite house auctions. One in particular is an early 20th century Schrade Cut Co Bone Handle Button Knife with U.S. PAT date of Dec 21, 09. When the button is pressed the blade opens to 90 degrees. My question is what is the blade supposed to open to? Is the blade supposed to open to 180 degrees or is it supposed to open to 90 degrees? Thanks to anyone who can answer this question.
