I agree with Virginian, the Case Bose collaboration knives are better quality than many customs selling at the same price or even higher. One of the things not discussed much on this forum is the low quality of some custom hand made traditional knives, but go to any knife show and you will see that many makers knives are different once in hand. Even makers who participate on this forum.
Of the Case Bose knives I have are two larger knives, Yukon Jack and AK Hunter, both in ebony and both have stood up to serious use in the kitchen, not just the bottom of a pocket or drawer

Plus, if you have any problem with them, you are backed by a company warranty that has lasted for generations.
Here are some photos that I think help illustrate this.
First we have an end view of a fairly high end factory knife from a well known and respected manufacturer.
In the half stop position, the spine is not flush. I see this to a greater or lesser degree on pretty much all of the factory knives I see which have half stops. Even in the best cases where it might be difficult to see in a picture, your fingers can feel it when you slide them along the springs.
Next we have an end view of a Case Bose collaboration.
Perfectly flush in the half stop position. My fingers do not feel any protrusion.
Next we have a full custom knife by a very well known and respected maker who posts here at BF but shall rename nameless.
Once again, the spring is perfectly flush in the half-stop position.
But notice how the top area circled in red shows that the springs have different heights/widths than each other, AND for some reason

the center spacer is abbreviated and does not extend to the end of the knife.
The problem can be more easily seen in this spine view of the same knife.
The end of this knife is, IMO, a mess. Nothing lines up. Nothing is even. And there is a small gap between the main blade and the bolster. And, again, this is a full custom knife from a well known maker who posts at BF and I would venture that most folks here know, and which sold for more than $1500!
For comparison, consider this same view of the Case Bose collaboration knife whose end view was shown above. Look at how clean and even it is. Far superior to the expensive custom knife.
Again, I do not believe that pictures can tell everything about a knife. But here, IMO they do tell
something.
