I thought I'd share my review on a dealer's website (Chestnut bone, CV version):
"I'm going to give you the bottom line first so you don't have to read all of this review to know what I think - If you are looking at this review, just go ahead and buy it, now, here - it's that good.
Now on to the review. First the CV in the description refers to Chrome Vanadium, which is the carbon steel alloy that Case has used for at least a very long time. It is a very good grade of non-stainless cutlery steel known for being easy to sharpen and holding an edge. So, for die hard Case fans this is a positive note. Also in this instance, this particular version of the Tony Bose design also happens to be the least price version Case offers. But being the lowest cost doesn't mean they have skimped on this knife.
I purchased my SB jack, this version, several months ago. I can honestly say I feel like I got more for my money with this purchase than any knife purchase I have ever made. This knife gets 5 stars because there are not 10 to give. I was blown away by the fit and finish of this knife, just perfect.
Now, what about the technical aspects of the knife? Well, closed length is right at 3-3/16" and overall length with the master blade open is 5-1/2" tip to tail. The master blade is 2-5/16" from tip to bolster, so this knife should be legal carry pretty much anywhere in the world regardless of how ugly the carry laws might be where you live. Notice that I did not say it is legal where you live; you have to determine that for yourself. The pen blade's shape is perfectly mated to the knife and just barely over 1-13/16" from the bolster to the tip, and a quite useable length. The blades have well positioned nail nicks and both blades have halfstops. The backsprings are flush with the liners with the blades closed, open and in the half open positions (on both blades). The blades are highly polished and finished and furnished shaving sharp.
My knife measures about 7/16" thick and the overall height and shape of the handle make this knife feel bigger in the hand than it measures and bigger than it looks. This knife is intended to be a light duty knife, but the construction has not been shortcut anywhere and can handle more than you might think when you first pick it up. I can say that it has not failed to do everything I needed to do when I carried it. Note: There are some days I needed a knife more suited to a particular chore such as gardening and then I decided to use a different type of knife like the sodbuster.
As I said earlier this knife is the least expensive version of the SB jack, but this knife doesn't know it and it doesn't care. I, on the other hand, am very happy about that and you will be too. The chestnut bone Case uses on these and other knives in the chestnut bone series is just about the best I've seen from Case in decades. I hope they continue to make this knife for many more years."
