I want to make sure everyone understands that what I am about to say is not criticism of the cold steel products. I own two CS knives and I am happy with both of them. I have also carried the Leek that is tested in this video for at least eight years. I have used it for everything you would use a pocket knife to accomplish. From opening amazon packages, to working on cars, to whittling and lite carving, to defending myself in the dark of night. It has never failed and I doubt it will ever fail in anything you would use a pocket knife to do.
Is the lock on the Holdout stronger than the Leek. It does look like it is stronger from these tests. Is the Leek strong enough for any sane pocket knife use? Yes, it is and I have at least eight years of using one knife every day to prove it.
If I lose my Leek, the Holdout will be one of the knives I will try in my pocket to see how it feels, I have no doubt about that. I also have my eye on a CS Kukri. But when you do these tests someone needs to say that you would never do anything that would put this kind of stress on a knife this size in a normal day.
