I got my PE and SE yesterday. I was very surprised how small the Navigators are. They look awsome and feel great. I was not sure how I would like them, because I've never handled the stainless handles. But I really like them. I have no concern about maintaining a secure grip.
The bad thing is the SE had a defect. I'm not sure if it's a spring or the lock, or something else. The blade was EXTREMELY difficult to open after the first half centimeter or so. It was so stiff the lock did not want to engage. Even when it did engage, it did not always pop up all the way. Also, the blade would not stay in the closed position. It would swing open that first half a centimeter or so, which exposed the tip.
I called STP yesterday evening and asked if they could exchange it. The woman gave me no hassles at all. She said a new one would be shipped out, and for me to ship the defective one with the return label that was in the box. I got the email that said the new one was shipped this morning, before I even shipped back the defective one.
I'm disappointed that I have to wait a couple more days. But overall I'm very impressed with the Navigator, and very impressed with STP--both with their prices and customer service. Although I should reserve final opinion until I get the new SE in hand...
