Not sure how I feel about that blade charging handle. Would rather it be less blade and more handle
The chagrining handle does not seem to be shaped too differently from that of an AK, so I doubt it'll be a significant problem especially if the new rifle has a a bolt release.
This is the chagrining handle that my VZ58 has, and I never really have any problems with it. In fact I like it even better compared to my AR-15 if I am not using the bolt release.
In my opinion, the shape of the chagrining handle (skinny or fat) does not really affect the "felt ergonomics" of the bolt, I believe the length and the location of the charging handle matters more.
Sufficient length of the charging handle ensures that you can get more than 1 finger, or using the palm of your hand when pulling it back during reloads. If you are using 2 fingers or the palm of your hand to pull back the charging handle, it is typically not a problem. If the charging handle is too short, and you can only pull it back using 1 finger, it can get pretty painful pulling it back after a couple of reloads.
I have used the Type 97 (export version of QBZ95 in .223, dimensions are identical except for the mag well) and my biggest complaint is the length and the location of the charging handle.
On the Type 97, the charging handle is too short and its location is too awkward to be operated comfortably. If you have used it, you will notice that when you pull it back, you are mostly using the force of a single finger due to the short length of the chagrining handle and the awkward carrying handle above it. This is okay initially, but after a few reloads your finger is gonna be extremely sore and you do not want to use that charging handle again.
Most of the other guns have charging handles that are placed in locations in which I can utilize much larger portion of my hand to operate, so I never felt uncomfortable reloading them. In fact, I don't even think about the charging handles on many other guns (Tar-21, UMP, G36, Type 81, AKs, AR-15s...), but the charging handle on the Type 97 is pretty problematic that it is the first thing I begin to notice after a few reloads.
So for the new rifle, honestly, the charging handle does not look too bad. I feel like I'd enjoy using that charging handle if I'm switching from a Type 95. No more sore fingers, hell yea.
You can also use after market upgrades on it if it really is a problem, a lot of Russian Spec Ops use this thing on their AKs, looks pretty neat.
