+1 The trick universal in the Portland cycling world is to make "pokey tools", sharpened spokes. They work perfectly. You can staple housing to your tool wall or whatever and just slip your pokey tool in it for easy access.
That this hasn't been mentioned once in this thread blows me away. With the tool, you only need to grind to a nice square end to fit the stop. No additional grinding to get to a good clean hole.
