Measure the bar diameter at the insertion point into the stem. Not sure, but I have a feeling it might be different from the current standard. There are a ton of Asian bar and stem combinations floating around in the used parts stream that will work on that.
If you are really attached to the original bar for some strange reason, and are going to toss the stem anyway, just use a pry bar to pry open the clamp end of the stem by inserting it into the slot.
Agreed. If someone started SAWING into the stem, it's trash anyway. No harm in destroying it the rest of the way if you really want the bars.
Actually, the penny method above won't work since your stem uses a nut and not a threaded section. Your best bet is to use a large screwdriver.
I often find that mounting the stem or bars in a vice helps tremendously. I use the side of the vice meant to grab pipes and only clamp as much as needed to hold the part in place.
