Spyderco Q's

To me this is the one that started it all. My brother gave me this knife after talking with him one christmas. I had to search on the internet a couple of days just to find out which model it was. Once I did, I found out much more of these little beauties as well as Spyderco as a company. This is probably the most common blade style, but I also believe the most popular. I don't know how many of these were made.
