Me too- I only took it out that one time. Well, that and the other time... and whenever I need to get into the saddlebags or need fuel.
One time a neighbor asked me to use the stove knob key to help him pry a boulder out of his yard but I wasn't falling for that one, no how, no way. I know what could happen using that key for such a purpose- it is so weak that anything weighing more than, say, 14,000 lbs. could bend it. But I think if you just use to open locks around the bike and dont' pry things / kick it / drop it and run it over you should be OK.

Betcha won't do THAT again... I think my stovepipe key has been out a couple of times in the past 4+ years...
