I think it is the ultimate evolution of the commando dagger. It is designed for one thing - close-in combat. It's an update of the Case V-42 Stiletto. The V-42 had a choil with a thumbprint so that you could pull in the blade side of the guard without cutting yourself. The V-42 had a pointed pommel, but many commandos would grind it down after poking themselves with it, so the Besh Wedge has a squared off pommel. Both were made by Case, so I suspect they use the same steel. The V-42 was hollow ground, but the point of Besh' grind was obviously not just to increase the strength of the tip, but the edge of the blade as well, so the Case Besh Wedge is flat ground. I think the original Besh Wedge (and also the Boker Besh Wedge neck knife?) went to a straight tip like a sharp flat head screwdriver, but the Case Besh Wedge goes to almost a small tanto shape which is interesting because it does have a point rather than just a small edge. The Boker is a smallish neck knife. The Case is a full sized combat stiletto. The main problem with the stiletto that the Besh Wedge addresses is the fragility of the point. The scales (covers) are removable and you can wrap the handle in paracord. Although I haven't seen an example of this, that means that you can also turn this into a very effective spear.
So, in terms of updating a classic, I think they did a fantastic job. I think they addressed every issue with the original on which it's based, and I think any WWII special forces commando would have chosen this over anything else available at the time.
The problem with this pattern is that it is so highly specialized. It has an extremely limited market. They say it's appropriate for law enforcement, but don't think many SWAT cops would use this. I haven't seen a study of this, but I suspect they tend to go for tactical drop point, clip point, etc. Certainly no beat cop would carry this every day. They tend to go for "rescue", scrappers, rope cutting, etc. Collectors might be interested, but they tend to go for original designs for the history and aesthetics rather than practicality, especially for a pattern who's most practical use is quietly killing someone. The 6.5" blade length puts it into the "Restricted Carry" category (anything greater than 5.5") in Texas and probably lots of other states limiting the age of the carrier and where it can be carried, so it won't be as popular to carry as a "Texas Legal" knife in Texas. It's not really a great survival pattern, although your could probably do lots of chopping with that flat grind, and you have a bit of choil that might be sharp enough to strike a fire.
It seems that the primary target user for this knife is a modern elite strike team. I think Case and Besh were hoping for a military/government contract, and may have gotten one, but Case decided to go ahead and make them available to the general public to clear out their stock.
Ignoring price for a minute, this is probably a better home defense choice than a bat, or a sword, or a kitchen knife for someone who can't, or doesn't want to, own a gun. It is specifically designed for close-in combat, not for hitting balls or cutting up a chicken. You wouldn't want to be on the wrong end of this blade guard.
