I Should Have Learned by Now

Anyone know the trick to opening those stitched bags of bulk rice? The one above is just an example; the rice I buy has double and sometimes triple stitching. And I'll bet maybe twice in my life I've been able to pull the right string and unzip the bag. Usually I end up going Charlie Sheen on the bag with a steak knife.

There's even an E-how article on un-stitching the bags but their method (cut the knot at the end, then pull the unraveling string) is useless.
