Dots Caused by a Prop?

I've been working on a character and my recent renders started getting strange dots on the face that weren't there before. Through some troubleshooting it seems that the blade that I put in her hand is the source of the issue. When I have it visible then dots will appear on the side of her face that is facing the blade. Hiding the blade removes the dots.
Knowing that the blade is causing the problem I have tried tinkering with the surfaces tab to tone down reflectivity and such. I also searched the forums and tried messing with fireflies on the render and although the dots seem to change position a bit when I edit the firefly settings, they are never eliminated.
For now I am doing two renders where I render without the blade, then with and cut the blade out and paste it over the render without dots. It gets the job done but it is not an ideal solution. Is there something I can do to the blade prop so that it isn't putting dots on the right side of her body? Note that my render would be bare like this -- I'm not putting in backgrounds or lighting for scenes or anything.

I would guess it's reflected light, that hasn't been converged yet. Probably need to cook the render a bit longer to get rid of them.
I tried turning up the resolution so it took longer to render and those little fellas stuck around. Is there a way to have it continue rendering after it says it is done?
Or is there a way to turn off the reflected light?
The easiest way to control how long a render cooks, is to go into the progressive rendering section of the render settings tab, turn off rendering quality enable, and put the max time to 0. Rendering time will now be controlled only by max samples. If its still noisy, just increase the max samples.
Also it would be beneficial to up the convergence to say 99% if you reach the max samples and still have those dots
I changed the render time and did the convergence thing... it took about 4x as long, but all dots are gone. Thanks TheKD and Coryllon!
