I love my Tomahawk! Good flipper, and you can feel it lock into place. It releases a little light off the detint due to the weight of the blade, so it takes thought full force. Mine has never missed locked up. Its a great reverse deploy-er, and it can be performed in a fluid motion to a strike with some practice. Like Randomsmack said, it closes without mercy, so pay attention when your first getting started with it, as the weight of the blade alone can cause serious injury. The one I have is in D2 steel, and it has held a great edge, and with a touch up from a strop every now and then, it will keep that edge well.
This one being a VG10 Folded steel (Folded as the real Damascus steel recipe went the way side many years ago), should do a good job too, given that its done right (Which from the Pic looks to be the case).
I would highly recommend this knife to anyone looking for a good size folder, with a great cutting edge that doesn't compromise on control. When you open this thing for the first time, you will smile! (Unless you short stroke it and the blade falls back on your hand, so show it who's boss!)
