Laurence,
I see your point.... so a real life lateral strength test would involve clamping the blade at some point ......60% from pivot pin and pulling down on remaining handle just behind locking mechanism.

So here's a question since you're so keen on FEA.
Have you bothered to model a standard well built folding knife pivot and lock, let's say a sebenza for example, and stressed it to failure in order to tell whether or how much stronger your design compared to the current standards?
It's all well and good to say your knife models at a particular strength, but without other data points it doesn't tell you whether what kind of improvement you're looking for. Are you operating in a vacuum or have you already done the virtual comparison as a first step to doing it in the real world?
I'd be more willing to accept the claims of superiority based on model results if you could at least show a comparative results in your model.
The first step in solving a problem is delineating what the problem is. You claim your problem solves the issue of lateral weakness in folding knife design. Just how big a problem are you solving? I don't know. I don't think you know either. Maybe that would be a first step. Think about late night made for TV marketing. First they show you the problem. Then they show you how their new product fixes it. That's how you end up buying something you didn't know you needed.
I don't know that I need a laterally stronger pivot. If you want to sell me a knife based on that, you have to convince me that I have a problem you are going to solve for me first. Then show me your solution.
