    I want to rate this knife as 4.5, but there’s no option.

    I really like the quality of this knife. The little touches like rounding the spine of the blade, the choil for finer control and the jimped back plate with lanyard hole and the thoughtful cut out of the scales around it. There’s even a small champher where you thumb would go to release the lock. In the review I watched, the reviewer complained about the sharp point on the end of the flipper. I didn’t find this to be a problem at all. I also appreciated the fluting on the flipper for added traction.

    Finish on the titanium is a nice tumble except for the clip, which is satin. Blade finish is a nice polish.

    What I didn’t like about the knife is the pocket clip. It takes just a little too much thought to clip it in. I also have a hard time with the spring tension for releasing the lock to close the blade. Also, if you are not right handed and prefer a tip up clip position, this might not be the knife for you as there are no other clip options.

    Those are small things, but in a knife that is as well thought out as this one, the small things stick out.

    I had a good experience buying from Collector Knives. Shipping was timely and the price was very fair. I will buy from them in the future.
