I really love Surefire, the company, and do not mind their pricing. Just to take a jab at this design, I'll ask: If you need a fork, why not buy a spork instead? The spork is also a spoon, and even though you only wanted a fork, isn't the spork better? IOW, for the love of all that is holy, I wish crenellations would die and stay dead. If you buy a flashlight for physical defense, you're doing it wrong. A flashlight is best as a lighting utility, and any other Swiss Army sort of design ideas tacked on for whatever reason, it can only dilute the prime purpose. At least it does not include the ubiqtous bottle opener found on nearly all things that are intended for something else (seems like).
Otherwise, nice update on the driver, even if it steps down. Nice to see E series is still being developed.
