There is no perfect tool for every job. There is no perfect knife for every job. There are knives that do the job that they are designed for better than others.
What makes a good working knife?
The most important feature is that is not limited by it's intrinsic material and construction. My old EDC (Everyday Carry) knife failed when I tried to pry a staple out of a 2x6. It turns out that the lifetime guarentee is only against loss. I could lie and get a new one, but what good will that do if I NEED it and it breaks again?
The second most important feature is it's edge design. Does it fit where it needs to go? Does it cut what it needs to cut? Does it's design make the job easier or more difficult?
The third aspect of the design is safety. Does it have a guard to prevent you from slipping and slicing you hand? Is the handle indexed so that you can know where the edge is without being able to see it. Hunting and camping knives can be used in situations that interefere with vision and they can get wet and slip. A good knife must minimize the risks that it's user is exposed to.
The fourth priority is comfort. Will the knife make your life more difficult? Will it cause you to get sloppy, trying to use a less painful grip that is unstable? Sometimes this is determined by the knife's purpose, or it could be easily identified.
The last priority, which ideally would be irrelevant is transparency. How do you know that the knife is as good as you think?
How is it tested?
How many cuts of rope can you expect before having to sharpen it?
Does the edge have enough toughness to handle the needed task?
Will the blade hold up to lateral forces?
If the blade is forced too far will it bend or will it break?
Is the steel forged as well as it should be?
Is the blade guarenteed? What are the terms of the guarentee?
Etching
Etching a blade is a gesture of complete disclosure.
A blade that has been forged at low temperature will develop striations that have been misinterpreted as welds. These striations form a fingerprint of the blade and they help you read the heat treatment and craftsmanship of the blade.
Etching striations form perpendicular to the hammer blows. The should form bands parallel to the edge from the ricosso (the softer unsharpened edge between the guard and edge) to the very tip. If the bands continue straight off the edge of your blade, then the blade was either ground off of a bar (not forged by the maker) or was repurposed from a failed blade.
There will also be a difference in the etching between the hardened steel and the tougher, unhardened steel. An etched blade will show the margin at the edge of the hardened zone. If the entire blade is hardened, then the edge must be tempered to avoid cracking the blade when it is stressed. If 1/2 to 2/3 of the blade is hardened, then the edge can keep a greater degree of hardness without making the blade brittle.
Etching will also help you see imperfections in the blade, such as cavities and cracks that would doom a blade from the start.
In use, these striations help resist cracking and breaking much the same as a wood's grain will.
Notice the waves that parallel the edge of the blade. This demonstrates that the blade is aligned with the grain. The grain alignment strengthens the blade. Careful attention to the grain of the stock is necessary for stock removal knives, but all forged knives will have the grain aligned.The handle of this knife is designed to fit your (I mean MY) hand.
This one is fitted to Katie's hand.
