There are several challenges coming up and several on-going. The idea is to carry something that takes you out of your comfort zone. Like carrying a Classic for a month and nothing else. I just finished a 108mm challenge. Now that really wasn't a challenge for me, since I have carried one every day for ages. It was still fun.
There are lots of badges that you can earn without posting for a month straight. Something like the flashlight badge only requires one post. Start a thread and write a little about your everyday carry flashlight. Plus a picture. Read about how to request a badge and when you make your request leave a link to your thread. Eventually you will be awarded a badge or not if you didn't fulfill the requirements.
There isn't a challenge for your SwissChamp coming up. If you have Leatherman or Gerber multis, there are some of those. Read some of the threads others have made requesting a badge of some sort or another. If you find time, read the posts for the Sportsman challenge that will finish up in a few days. See how a 30 day challenge is done. Fun to read anyway. Best wishes. G
