Queen Cutlery has been around for a long, long time. I find it somewhat shocking that they have never quite reached the level of relative success as their contemporary, Case. This particular model, a #18 "Heavy Jack" is from the 70s.In spite of being 4 decades old, the spring still have very strong "snap". The Winterbottom scales are showing a little wear...but overall, this knife is in really good condition and could perform, day after day, just as well as it would have when brand new.
