I am impressed with my MPC folder so far and yes, bombproof is a good analogy. As far as the folders go, take all the hyperbole and bylines from every one of the production tactical knife makers, and some custom ones, and you can apply them all to this line of knives in earnest. These are knives you need to handle to understand.
The lockup on this is one I have implicit faith in - beats your standard lockback, framelock and liner lock all rolled up into one. This does become the proverbial fixed blade. You've got 1/4" thick worth of solid steel contacting more 1/4" thick solid steel completely. You've got a thumb rest area that actually reinforces the lock further as you bear down on it (not that it needs it) And if that's not enough, you can physically throw a safety onto the lock, in either the open or closed position.
MPC stands for Multi-Purpose Combat folder. It's a hard use folder that lives up to the name of hard use. It might not be everyone's cup of tea, as it's design is very military in a modern sort of look. Sort of like what the Marines in Aliens II would have carried, or what Arnie the terminator would pull from his jeans.
For me, it's a nice addition to my other knives and I will be looking forward to challenging it in the outdoors soon.
