Black line around mask

Hello all !
On a video made with Keyshot, I want to place a towel around a blade.
To do so, half of the towel should be behind the blade, and the other half should be in front of it.
To do so, I have created one "addition" mask on the blade. I then copied the layer containing the addition mask and paste it.
On the paste layer, I changed the mask from addition to "subtraction". The shape and movement of both masks are thus exactly the same.
Here are pictures of the addition and subtraction masks.
But there's a problem. On AE composition and on the rendered video, I get this black line around the blade.
How could I remove it, or at least make it less visible ?
