I Screwed Up

OK thanks a lot for the input. I figured cords were generic, but helpful to get confirmation. Will give the repair a shot today!

A newbie here, hope you folks can help. You know how at the end of the day, when you've already worked a hour beyond when you should have called it quits, but you think "well, let me just cut this one more board and then I'll be done." Well I didn't pay attention to where the power cord was, and sawed right through the cord. Nice fireworks display aside, this is my husband's brand spanking new circular saw and he's going to be pissed. On Saturday we had planned a long day of work on this project, so I really want to get this blunder fixed by then, which precludes mail-ordering anything. Replacing the cord looks pretty easy and within my skill set, but I'm not sure I'll be able to get the right cord locally. Are the power supply cords fairly generic? Seems like they should be, but when I looked online for parts lists for skilsaw, each model seems to have a different part number. So, am I wasting my time if I just buy a generic replacement cord or even simpler, swap out the cord from my old 5" saw)? In other words, do I *really* need that exact official SKIL part? It's a 7 1/4" HD5687M, if you need to know the model # to answer. Thanks in advance for any advice.
