mikemck,
Here`s a general review as you requested:
The Orca is best described as quite heavy, weighing 11.3 ounces (and 17.3 with sheath!) at an overall length of a little more than 11 inches. The handle is relatively big , you`ll never have problems getting a grip on it , no matter if your fingers are cold, what kind of gloves you wear or whatsoever. ( The finger groove isn´t that disturbing, either. The only problem I have with that handle is that, with respect to the chopping edge on the knife´s back , its end shouldn´t be so slim.) The tang runs through the entire handle (as you surely all know), and its end is applicable as glass-breaker.
The apparently non-serrated part of the blade is , in fact , micro-serrated (about 13 teeth per eighth of an inch) , thus being very effective on ropes, belts and the like. The tip is pretty rugged , but provides very poor penetration abilities ( that is why I would recommend it for divers and rescue applications). The chopping edge is not sufficiently sharp to actually cut , and it is, unlike that of the Orca presented at the 2001 Nuremberg International Weapons Exhibition IWA, entirely PVD-coated. (My Orca was also produced in 2001 , so I suppose the knife presented at IWA was the prototype).
The sheath provided by Boker consists of two separable elements , one of which conceals the blade , securing the knife with a bolt that has to be operated with your thumb. This alone is sufficient to carry the knife, but there is an additional sheath element attached to it , which additionally secures the knife with one of those rubber rings. Though the sheath can be attached to most regions of human bodies, the location should be chosen with care, since it is quite difficult to operate a thumb-operated bolt with the opposite hand! ( Especially important if you carry this knife in cars as a rescue knife; always remember one arm could be injured in an accident!)
(Describing this odd sheath is very hard, especially since English is not my native language; I hope nobody noticed that so far...)
Regarding the question of proper uses, I have to state that this is a specialized tool for divers ; I also consider it the best rescue-knife available. It isn`t easy to find anything it cannot do, but for most ordinary applications ,any hunting knife is more practical.
I merely carry it just to be prepared .
P.S. : It cuts tomatoes without squeezing them , too!
