The high Rockwell will hold a razor sharp edge longer. A good tool to clean a knife is a toothbrush. Whenever you upgrade your toothbrush put the old one right next to your sharpening equipment and use it to get all the crud off the blade and inside the handle before you put a new edge on it. You don't need to lather the blade in oil when you have completed the sharpening process. Use a high grade honing oil and just dab a drop on the blade's pivot point when you're done sharpening.
Price can be a factor for the knife buyer.
Again, realize you get what you pay for. The pocket knife becomes a part of you, like a well-trained dog, or a finely fitted shotgun. The perfect pocket knife, in my book, gives you a sense of security that nothing can go wrong that you can't fix, open, or cut. All rights reserved.
