Oh my, they had you shucking corn the hard way. lol
By far the best way I've found to deal with sweet corn is to boil it in the shuck. Pull it out, dump it in an ice batch until it's cool enough to handle, cut the butt of the ear off with a sharp knife and peel towards the top. There will be very few silks left behind and those will usually come off with a quick rinse under running water.
Like peeling a banana upside down to catch the strings; you know, like monkeys do! :)
