Thanx Vivi. Very nice....to experience...and to watch you have the experience.
A little Police history might be fun:
We introduced the "Marirner" model in '82. (The name of the Mariner was eventually changed to Rescue). Really the first push at a serrated pocket knife for everyday carry. It took a few years to refine the serrations to where I wanted them, but all in all it was a big leap. We were already pro LEO's, Fire & Rescue, and the teeth would bite through stuff that even sharp plain edges had a hard time cutting. Law Enforcement came to us and asked for a Mariner model, but with a point. My preference was for a 4.0" blade so that's where I began the design. I took the straight edge of the Mariner, added a point, added a sharp edge on the spine for the first 3/4" of an inch, "Dagger ground" through the center for a sharp strong point. then I wrapped the handle around the blade, covering the sharp tip on the spine with the handle, so the exposed sharp edge was covered , and tried to make it as ergonomic, yet as slim as possible and still be very high effective performance. The design took quite a while.
Finally, my perfect pocket knife....for me. I thought about calling it "LaSalle", but decided that was too egocentric and opted to call it the "P.I.G" instead. (Pride Integrity Guts). We made 2400 pieces before we changed the name, due to complaints from non Police customers. The first 1200 pieces had to go back because they defeated on the spine tap test (Yes, we spine tapped back in the early 80's) and they had to be remade. We made both right and left handle models with the lefty being the reverse of the right handed version.
Now the Police 4 is the latest and it's really a design for me, all restraint aside. It's my preferred carry most of the time, but I have to be more careful as it's blade size in not appreciated by some, though it carries like a smaller knife.
Just an FYI.
