Hi there anonymous:
I'm not sure why you state you feel someone who owns them is prone to be biased or less credable, they either like it or they don't, for many reasons, like any other knife.
If they own one they may just have more knowledge of the knife through carying it than just handling one at a show, but I'll attempt to give my unbiased impression to answer your question anyway.
I have owned my MPC for 4 days, have carried it for three days in the pocket and clipped on the waist, dependant on the clothes I'm wearing at the time.
The knife is huge, it's heavy, it's built like a tank [ to paraphrase another dealer, and to which I use as well as it is a correct statement.
The handle: I have not worn gloves since I have had it. There is not one sharp corner on the knife handle. All edges have been radiused well. In the closed position, it is comfortable and a hell of a load fist, especially with the glassbreaker at the end of the handle. It's a handful of a folder, and the biggest folder I own dimentionally.
I bought it site unseen from my distributor and did not know if I would like it or not [ the handle and the overall knife for many reasons.
It is blocky, but not rough to the hand due to the well radiused edges. The handle will not be prone to twisting in the hand due to it being blocky [ squarish ]. The hand will be able to hold the knife while twisting the blade into or out of hard targets, and will not be prone to rotate in the hand. That translates to better control under extreme conditions for me. Thats a good thing as I have more expensive folders but they are prone to have to grip them very tightly if one is twisting the blade [ torqueing ]as the handle wants to follow the blade, consequently you need to put a death grip on some folders to prevent this. Not so with the MPC, and I like that a lot.
I imagine there will be many people who, for whatever reason, will not find it to their tastes in folders. I know I do not like some knives that others rave over on the forum. It becomes personal preference to the individual and what they are accustomed to in the past and their experience level in using a knife [ whether that be in a serious self defense role or as a hard use utility tool ].
The handle sits about an inch out of the pocket when carried cliped, enough to grab onto and withdraw it. Some do not like that feature and prefer a folder that sits deeper in the pocket and is less conspicuous to the catual observer.
I've never been one to worry about such things myself so thsi is okay for me. Also, if it sat any deeper, it would be more difficult to draw it due to the weight of the knife. One needs a good finger purchase here due to the weight or it will be prone to clumsiness [ at least for me ]. There is a lot of knife below the clip and in the pocket.
I have worn it with Dockers and dungarees. It does not touch the bottom of the pocket of either, is slim enough to still get into the pocket alongside the handle if carrying something else like change or a money clip, and rides better [ weight wise] than I had thought it would on the pocket.
There are a few things I would change on the knife if I had a preference, but the handle is not one of them.
I have decided to continue to carry the SnG on the pocket for defense and keep the MPC on the waistband at IWB holster position for the the times I may a folding crowbar with an edge.
Hope that helps, I'm not sure what you are looking for. If you want the toughest knife [ folder ] that I have ever handled, you will like it for that value alone.
I thought my SnG Strider was tough, and it is, it's just not in the same league as the MPC for many reasons.
I carry an E2 surefire at all times on my belt, yet rarely have need to use it. The MPC will take on the same role for me on my waistband. If the balloon ever goes up, I'm caught in a building that goes dark, that I can't get out of the elevator or situation I'm in, the E2 and MPC will let me "see" my way clear while I extricate myself from wherever I find myself. Using the passive crossbolt locking mechanism, it becomes at least as strong as many of the high end straight knives one would think of in a dire emergency relative something they would choose to have available at such times.
Stay Sharp
