So I voted "yes". If you just take the two models in isolation from all the other multitools, there is no reason why the wave and the arc can't coexist. The real question is whether the wave can continue to exist when there are so many cheap clones now that the patents on it are all expired.
Another question is whether the arc and the charge can coexist. A lot of people are comparing the two and are coming down in favor of the charge over the arc, both in terms of cost and in terms of the toolsets. They're saying the charge is better than the arc. Personally, I would only agree if the charge had an awl. However, you can modify a flat leatherman bit into an awl if you have the time and the inclination...
This has been posted before, but thought it could be re-upped again.
It's important to understand that while you're gaining some edge holding with Magnacut, you're also GIVING UP a ton of toughness by going away from 420HC.
There is a reason multitool makers use 420HC on all the tool impliments, it's a darn tough steel.
What do you value more on a multitool blade? Edge holding or toughness?
Definitely toughness. It's why most of my knives are sharpened at 20 degrees per side. The fun thing about this is that knives with more acute angles can easily be reprofiled to less acute angles over time. You only need to keep sharpening them at the wider angle. At first it starts as a micro bevel, then it becomes a secondary bevel. It takes a lot of time to do the opposite by going from a wider angle to a steeper angle, and the edge becomes more fragile when you do that.
I know there are a lot of people who sing the praises of steep angles retaining sharpness, but this requires a higher quality steel and/or lighter use, such as you would see with a decent kitchen knife.
When it comes to super steels, there is a good case to be made for heavy use situations like with bushcraft, or maybe in some professional settings, but in my mind it doesn't compensate for the greater ease of sharpening the so-called budget steels. Magnacut was put forward as the exception to this. It's supposed to be a super steel with awesome edge retention and a greater ease of sharpening (and superior corrosion resistance on top of that), however it's still not justifiable when the cost is so high and the actual blade is so small. When the blade is not suited or designed for heavy use, there's no way I can see to justify making it from a super steel, especially when it raises the cost so much.
There's a place for the arc, but it's not what everyone thinks it is. In my opinion, the toolset is far more appealing than the knife steel, but most of the focus is on the knife. It doesn't make a whole lot of sense to me.
I don't think it makes any sense for the small light duty knives that you get on multitools.
