Thanks for your Post, Marcus. Here are the answers you were looking for.
First, the simple questions. A2 Grade Tool Steel. It is triple-tempered and Rockwell Harness Tested 59-61. I use this metal because it holds its edge very well, yet allows the layman to re-hone it. As for zoning, differential tempering is done to larger blades, and I'll do it to smaller blades too per request.
Now the harder question. Where's your money going? First, the prices aren't solely for a blade, as those other blades that are half the cost. Instead, you are getting a complete system. Let me dissertate for a moment on what exactly that means. A complete system does not mean that you're just getting a blade, a harness, and a sheath. It means you're getting a sheath that was made for the harness, both of which were made for the blade. Everything is intricately engineered to give you the utmost comfort (if you don't wear it, it won't be much use), speed, concealability, and overall effectiveness. That's where part of your money is going.
The rest goes into a blade that has been painstakingly designed to the highest quality standards for its intended use. Remember, Marcus, there is no difference in the design side of these blades from my JSP line, except that I don't do every step. That means that you are getting a blade that is better, sometimes only by a hair, than anything else out there. But my philosophy is that the extra "hair" could make all the difference.
If you are still hesitant, please read what others have had to say about my systems and products, and follow up with current Blade Rigger customers on the forum. Ask them. They'll be able to tell you better than I where your extra money is going.
All the best,
