I love my Umfaan. The only thing I would change (and did) is the thumb stud. It was just too small and sharp. I pressed out the original stud. I didn't know what size I wanted in there so I started with a 10-32 hex head screw. I just turned down the thread a little and pressed it in. I carried it for the last few months (using it for my EDC) like that. I really love the size of it. We got our first decant bad weather today (finally) and I had to use my Umfaan to open a bag of salt. I pulled it out of my pocket and opened it (and closed it) with one gloved hand. A beautiful thing! Now that I know what size I want it I will make a nice stainless steel one.
