The SERE 2000 is by far one of my top three folders, and I own nearly 30.
It was my first and only Al Mar purchase. I bought it without ever having handled one in person. When I opened the box I was SHOCKED!! This knife was BEAUTIFUL! I thought that it was too pretty to be functional... I was DEAD WRONG!! I took it out and opened it. The action was literally smooth as silk! Just as smooth as the best of my Benchmade Axis Locks which are known for their smooth opening. The liner lock clicked with a resounding "CLACK" fit the tang (or whatever that's called) perfectly, and was ROCK SOLID! The edge was EXTREMELY sharp and I didn't dare to "improve" the edge, because I knew there was no way I could get it sharper than it already was. I love the VG 10 steel, it gets REAL sharp and holds the edge for a LONG time!
This knife is heavy and I knew that when I bought it, but I don't even notice the weight. This knife is very solid and very strong. I have read some reviews where people have had problems with the SERE 2000 failing the "spine whack" test, but mine has never failed on me. The knife rides really low in the pocket which I like, but as mentioned before, it can be a little hard to draw. I prefer to carry mine horizontally just to the right of my belt buckle in a large Benchmade pouch. You can buy one for about 10 bucks. The knife fits in the pouch perfectly and is easy to draw and I just flick the thumbstud with my thumb and the blade swings open and locks into place.
I truly think you'd be hard pressed to buy a better knife for the money. I am going to buy another one as soon as I get the money.
I hope this helps.
