My Umfaan sits in my shirt pocket or front pants pocket at the office inside of the provide pouch. I had problems with my decorated small Sebenza: several office employees freaked out when I thumbed it open once, and airport security made me register it to get to the plane - they said, "What are you doing with such a big knife?" I now carry the Sebenza in my briefcase for larger jobs, and the Umfaan's small blade is quite adequate for everyday chores, though it's not as useful or goodlooking as the Sebenza.
This is my second Umfaan. I lost my Zig Zag Umfaan, and I swore I wouldn't buy another expensive easy-to-lose small knife. But I missed it so much I had to buy a replacement, an indication of what a convenient knife it is.
