Some people use there money clip a couple times a day if that, at the store, gas station, restaurant etc. Some people like myself are in a business that works with CASH and use there money clip dozens and dozens of times a day, hundreds of times a month, thousands of times a year putting money in and taking money out. The stress on the clip contracting and stretching dozens of times a day, hundreds of times a month, thousands of times a year is a true test of the durability and quality of the clip manufacturer. I have used money clips for over 35 years in business. I started with regular metal and even aluminum which the metal is not easy to work with and the metal has "bad memory" when stretched considerably by staying stretched out and almost impossible to bend tight again and the aluminum will stretch and can be bent back tight again but after hundreds of cycles of this it eventually breaks. I came across the Superior Titanium Clip a few years back and can tell you from the most rigorous use anyone could put a money clip through that this clip is truly SUPERIOR! With the choice of Titanium because of the lack of "bad memory" after stretching and the "good memory" going back to its original size works 2nd to none. I have purchased a couple of the T-Series / Viper Series in the T60 size and they handle the abuse of daily rigorous cash business use with almost next to no stretching. To be honest I have stretched a T60 slightly when I probably exceeded the 60 bill recommended usage by having cash and about a dozen business cards at the same time, but when doing business it is not normal to count the quantity of the bills but to count the quantity of denomination of amount of money. I can highly recommend the T60 Ti22 and Viper series for the majority of large cash carry but I probably needed the T100 at times and most likely would have prevented the stretch of the clip at all. If you want a clip to last and do what it is supposed to do, hold your money tightly with a few cards / business or credit cards then realize you get what you pay for and buy the Superior Titanium Clip, it looks great and the compliments from friends and people who notice it proves that and performs great in the most rigorous usage! To some of us it is not just a way to hold our money but is a tool in business we use to MAKE money!
