I'm not a big fan of bulky key-chains and the stuff I've got on mine right now is probably more than I really want, but so far it's not too uncomfortable.<br><br>In addition to my keys, I have:<br><br>International Orange Fox 40 whistle<br>SAK Classic (won it as a door prize at a company golf tournament 5 years ago)<br>Photon Microlight (red LED)<br>Key blank with 4 lighter fllints crazy-glued to it<br>The breakaway lanyard that came with the Fox 40, chainstitched so it's about 4 inches long<br><br>I also carry a credit-card sized Fresnel lens and a PSK-type can opener in my wallet.
