Esav - "stranded whale look" - LOL!! I know what you mean
OK, I managed to get one of the Alpha CrossLock PBS's in yesterday and it's quite apparent Buck has really improved on the CrossLock design concept. As Esav pointed out, the handles are anodized aluminum, which give the knife more lateral strength in the handle area than the original CrossLock.
The blades are outfitted with flippers and yes, you can easily flip either out. Which brings me to my next point. I was pleasantly shocked at how easily the blades open and closed right out of the box. They are glassy smooth! A MAJOR improvement in this area over the regular CL's. The open blade's flipper lines up with that of the closed blade's, in essence, forming a simple but highly effective hand guard. Lockup is solid though the liners kick on over too far in my opinion. But there isn't any wobble in any direction.
The shape of the main spear point blade is thinner than the original CrossLocks. This kind of surprises me with a hunting knife, as one would want plenty of belly to the blade. But that modified swedge adds to the knife's styling.
The clip is pretty long, making it easy to clip onto your pocket or a belt [though this is highly discouraged when you're out in the woods in acase the knife works it way off of your belt by itself]. Each Alpha Crosslock comes with a heavy duty nylon belt sheath with a button flap closure.
The saw blade's teeth are very similar to those on some of my larger, dedicated pruning saws. It has been my experience that this cross cut style of saw teeth are very aggressive yet allow for smooth push-andpull action. It should work as easily on bone as it does on wood.
The 420HC steel won't hold an edge as long as ATS-34 / 154CM, BG-42, or even S30V but it is very easy to keep sharp.
Overall, I have to commend Buck for improving the CrossLock concept with the Alpha CrossLock PBS. "PBS", BTW, stands for "Portable Butcher Shop". All of the older style CrossLocks have now been discontinued.
