An older design from Pat Crawford, but still as good in the hand as any knife I've ever picked up. Both the Wortac and the KFF have grips that are "out of this world" perfect for my hand. This one will get tapped for edc, and while it is a rugged design, Pat has "prettied" it up some! Back spacer and clip have a little filework that gives the knife a pleasing look while not being so much that edc would be out of the question. All the titanium; bolsters, liners, and clip are anodized a purple/blue and relly work to give the knife a covert look, along with the black micarta handles. Blade is satin finished S30V, as are all of Pat's newest folders, and measures 4.0" X .170".....big and beefy! The lock up is by liner lock and Pat has the formula down pat, pun intended, as lock up is rock solid. Liners are .065" thick and due to the design of the handle the lock is in no danger of being inadvertly disengaged. Clip is a Crawford design and is mounted high on the bolster for tip down carry and deep pocket carry. If you've never handled a Wortac it might be hard to appreciate the fantastic grip the knife has. Of course it was designed to be an integral part of your hand. Timberline does a great copy of the knife that faithfully recreates that handle. There is also an Al Mar auto Wortac that is also a faithful reproduction.
