Anthony :
Why are you assuming the ArcLite has a thick edge?
Weaker steels need a greater cross section in order to have the necessary functional level of durability. You either have a choice of making a blade which will cut at a lower level, or having the functional level of tolerable stress reduced which in turn reduces the scope of work for the blade.

In regards to evaluations done in this manner, the winner is easily the cheapest blade you can find. I can buy a Henckels paring knife for $5 Canadian, and in order for the ArcLite to beat it in a per cost ratio it would have to outperform it 5+:1, that is not going to happen.
You can make the same argument for any decent production blade and they all lose as the price rises. Compare the Bush Hog to a decent machete which you can get for $10-$15 dollars. Is the Bush Hog going to outperform this ~7-10x to one. No. However is it a better buy? Well there will be a performance gain, is this enough to account for the price jump? This depends obviously on the user.
Mike, I never argued the point that it was a poor choice for its price, or that the blade in general was not worth $20. This is something that I in general don't even think is sensible to discuss as it is akin to "what is a more attractive color, blue or red". Its worth depends on your available funds + the performance of other blades, above and below its price range plus other factors like how much work it will actually see.
If I was presented with the design I would pass on it for several of the reasons I pointed out in the above it is not a user based design which is all I am interested in. If this was not an option then I would chose the steel that either gave the largest profit margin to maximize the cash flow or the lowest tolerated one in order to present the user with the best functional blade depending on what the desire was for the manufacturer. Regular 420 is probably better in terms of performance/cost, plain carbon steel like 1084 is easily better in the same regard and a cord wrap eliminates the rust issue with the handle which would be the biggest issue.
As for the cost issues of several spects like grip texture and cord wrapping, they are way off unless you are contracting them out to someone who prices work similar to McClung. Anyone can learn to do a decent high pressure cord wrap which would cover the ArcLite's handle in about a minute. Assuming you are paying them a really decent wage ($25 per hour, far in excess of factory line jobs), that is $0.50 extra for the wrap, and of course the cost of the cord, which would be even less. Grip texturing could be done at cost similar or less than all those holes.
