Haze, I am not sure what you mean by double detent. Ben when I tell you the price you have to remember it was obtained at a yard sale. I paid $20 for it. I didnt know this could be this fun. I looked at the above link about fake compared to real and the box is real having bolder letters, the faded red lettering and the inside of the box is bright white like an original. Other comparisons on this link favor it being real but is not clear. As for me, my need to know is not financially motivated. However I need to know either good or bad, just because it will help me sleep better. So please continue I am getting a good education. I have always collected antique knives and hadnt even heard of Emerson knives before I bought it. I saw "made in the usa" on it and thought any American built knife should be worth $20. It wasnt till I checked their website that I learned they are favorable thought of and worth counterfieting.
