I love this thing. 
Rollin' flush with my single dollar bill. That's just how I do.
I stole the idea after stumbling across Leffot's Fold wallet when I was trying to find some shoe porn. Mine isn't nearly as nice as theirs. On the other hand, it didn't cost $100, so I'll call it a draw. I also got the satisfaction of a job-kinda-well-ish done. I made a quick paper prototype and then went to cuttin'. Part of the fun of doing a quick sloppy draft is that often times the quick sloppy draft is surprisingly good enough.
Like they say, "Simplicity is the ultimate sophistication". I loved the stripped-down feel. I will spare you the #lifehack #diy #dailycarry #tips about how I use it. You're welcome.
The point is, this thing is awesome. Now that I've tested and loved the concept, I'm considering making myself an upgrade with nicer leather and non-crooked cuts. And there's also the expected satisfaction that comes with generally trying harder---not to be underestimated.
Alas, the ascendancy of this wallet means that my previous favorite, the Backpacking Light/Simblissity collaboration, the LiteFOLD XP, is now retired. After 6 or 7 years of hiking and, um, sitting on my ass, the old wallet was showing its age. I still highly recommend Simblissity and will probably pick up another one for multi-day outdoorsy use. My fold is the new king.
