I've got an MPR and love it...Nope it's not perfect...the clip looks good, but isn't the best in function, but it works. It is also chunky and heavy at 5/8" thick,and ~5.5ozs but I can get a full four finger grip because of the width, and being in construction the weight or width doesn't bother me carrying it in my jeans pocket. If you like thin, light weight knives pass on this one.
It is certainly robust..just like it's name implies, a Mini Pocket Rocket! It has a thick Ti lock, and thick blade stock that I compare to a Strider. It has an adjustable stop pin so the lock can be adjusted as it wears. Although with the thick lockside Ti, I don't see adjusting it in my lifetime. The action, at least on my example, is butter smooth, lockup is rock solid, yet easy to release, and the blade is perfectly centered. While the weight, to blade length ratio turns alot of people off, it makes the MPR a legal to carry heavy duty EDC. I rotate this with my small Insingo as my daily work EDC, which gets carried every other day and don't see myself parting with it any time soon.
