I just got my Esee 4 three days ago with the Tek-Lok and thought the same thing at first but it DOES work. Here's what does work and doesn't work, using the provided screws and washers. First, what DOES work is attach the Lok to the Blade side of the sheath, not the spine side. ONLY 2 screws will attach, the Lok is too narrow to go all the way across BUT THAT'S OK. If you read similar posts they all will say the same thing. I know it might be kind of weird but it works great, VERY secure and stable, plenty strong. You'll get used to it. ALSO you have to remove the top sheath screw which happens to be the tension screw for the sheath because that hole has to be used for the top hole of the Tek-Lok to attach to the sheath. This will again engage the tensioner and it works great. If you try attaching the Lok using the rubber washers, it won't work, the screws are too short. If you try attaching to the SPINE side of the sheath it will go but it will stand off at a funny angle. IF you want to attach to the spine side of the sheath and use the washers you'll have to buy longer screws but that works. You'll probably have to get 3/8 inch screws, anything longer will stick through too far. SO if you try option number one though it will work great. I love mine, DON'T GIVE UP!!
