What kind of glove is being shown in the following pictures, and why is it nearly always a knife user who wear this style of gloves? I've been searching for information for the past five or six years on what kind of gloves that Ein is wearing in the following pics from the digitalized novel Phantom of Inferno. (She also wears them in the three episode OVA series, Phantom: the Animation).

I've noticed that this particular kind of glove is often used by knife wielders; such as Kuro from the Fate/Stay Illya series, Chloe from Noir; Yuna's sprite in the free SAO:IF app; and the Prince character in the manga Snow White with the Red Hair, just to name a few. I have more pictures that I can upload if that would aid anyone in recognizing what kind of glove she is wearing.

I've already tried google searching several images in my research-glove-comparison folder, but the only thing that comes close would be a middle-loop finger glove, which lacks the single, solid loop seen in the first and second images.

To boil this all down: what specific kind of glove is she wearing in the images below, and why is this particular type of glove -to the point of synonymous association in my eyes- used by close-combat knife wielders? 


  First pic is to show what the glove would look like from the view of the palm, and while holding a knife. (in the knifeless hand, you can see the loop part of her other glove)





  Second pic is to give a close up, side view of the glove.





  Bottom picture is to show how the glove fits around the middle finger, as also shown in the top picture.




I just desperately want to know what kind of glove she is wearing, so that I have that small, wonderful tidbit of information to add to what I know about my Favorite, dopamine-fuel-for-my-brain-every-time-I-think-of-her, character.
These gloves are called finger loop sleeved gloves but sometimes also referred to as (long) Fingerless sleeved gloves. 

They more often then not come with no holes at all, or with only a thumb hole. However the one in the picture is not unheard of either 

The image below comes from an ebay search on sleeved gloves, similar results can be found on amazon as well.
