Extrema Ratio M.P.C.

[lefthandblack]

Hello all, I just ordered an Extrema Ratio M.P.C. from www.thebrightedge.com brand new for $200. This is an awesome price and I am stoked. Does anyone have any experience with the blade? It looks like a tank. Can't wait till I recieve it. Thanks for any input.

i have a fulcrum11 and really like it, great knives imho, kinda hard to find right now, and expensive when ya do, good price too. a really heavy duty big knife, rides well in the pocket though. i bet ya like it. wish i could find a nemisis for $200.....

I've got a Nemesis, which is the same knife as the MPC, but with a narrower blade. Tank is right, these knives are massively durable.

Don't be discouraged by the thick blade, either. You can sharpen them to a decent edge.

Sharpen it all you want, unless you remove a lot of metal that thick a cross section isn't going to cut very many materials well.

Thats alright as I usually carry two folders, currently an Al Mar SERE 2k and an Emerson CQC-7. I will probably switch to the ER and the SERE and retire the Emerson. The Al Mar is a great cutter in my experience, so that blade will probably do most of my cutting chores while the ER is relegated to a backup defensive role. I just could'nt pass up such a deal as I have always wanted an M.P.C. just to have such a monstrous folder. Thanks for the input guys.

Ha ha ha ha ha ha ... no, Cliff, it won't shave the print off a business card ...

It was fun cutting up vegetables, though -- maybe my technique is just better than yours -- and it did fine in the woods, clearing thorns along the trail.

No, it's not a puukko. It's not a Sebenza. It's built for strength -- but it will take a sharp, if obtuse edge.

It cuts A LOT of materials VERY well. You just have to know how to use it.

 

[Cliff Stamp]

... it won't shave the print off a business card ...

It can do that easily, all that requires is a sharp edge.

...it will take a sharp, if obtuse edge.

Yes and lots of materials require more than a sharp edge to be cut efficiently.

Yeah, apply a lot of force to drive the 1/4" blade stock through it.

Easy! After all, I chew the ends off horseshoes so we can use them for ponyshoes instead ... I am SO STRONG I CAN DRIVE A NEMESIS BLADE THROUGH A CARROT, A POTATO, OR A SLICE OF BREAD, without breaking a sweat.

And some people think Cliff is only interested in sharpened pry bars....

....I CAN DRIVE A NEMESIS BLADE THROUGH A CARROT, A POTATO, OR A SLICE OF BREAD, without breaking a sweat.

I would hope so. I don't think I have every broken out in a sweat from food prep, however the effort with a knife like the Fulcrum on stiff vegetables is easily 10-20 times that of a knife with a sensible grind thus saying it cuts "very well" redefines the meaning of the expression.

Can you cut a carrot sure, if you don't do much cutting efficiency doesn't really matter, same with any type of work in general, if the volume is low it doesn't matter how much effort it takes because the total output is still low. You have to shovel a wheelbarrow of crushstone you can do it with a small hand spade, try to fill a basement though and your perspective changes.

I recently spent a few hours cutting up rhubarb using the Fulcrum alongside a few other knives doing runs of 500 cuts, it required 5-15 lbs of force compared to 0.5-1.5 lbs. One cut it doesn't matter, 500 gives you a different viewpoint.

It has one of the lowest cutting grinds I have seen on a knife, and will only cut well on materials which are not influenced significantly by geometry and just depend on sharpness like meats and thus anything will cut them well as long as it is sharp.

It is also overbuilt to the point of simply detracting from its performance, even with a full height flat grind the strength it would be overbuilt for its blade length.

Of course you could say the Fulcrum cuts "very well" and just define other new terms like the Paramility would then cut "badass well", and the Opinel cuts "nuclear well" and so forth, just like all steels are tough and hold an edge well, some though are just extremely super tough and stay sharp really gnarly long.

And some people think Cliff is only interested in sharpened pry bars....

Sharpened pry bars have their places, I just would not say they cut very well, just like I would not call a Deerhunter suitable for prying because you could dig in cheeze with it.

A slice of bread, sure. A potato? Maybe, but a carrot, c'mon now Esav, I think you're exagerating badly my boy. Tch!

 

[Esav Benyamin]

No exaggeration -- not just any carrot, either, but a RAW CARROT!

The problem with Cliff is, he has absofreakinglutely no sense of proportion.

 

[Zerileous]

lol, thanks for the entertainment Esav.

 

[Brian Jones]

Keep rockin', Esav!

 

[ANGRYMOB]

Anyone remember ol' marcus welby in those coffee ads??? "Why so tense Cliff, too much caffeine???"

 

[SIFU1A]

well mine cuts just fine, let me tell ya.

maybe ya arent sharpening yours correctly??

whats so great about opinel?? they are ok but imho dont cut anything any better than the ER, hardly "nuclear" lol.

 

[lefthandblack]

Just recieved the M.P.C. in the mail. This thing is a monster! It makes my SERE look like a toy! I can see what Cliff is saying about the knife being overbuilt, but that kind of appeals to me. I could dismantle my house with this thing! When it locks open, it feels like a fixed blade. I could'nt imagine what it would take to make this lock fail, especially with the crossbolt secondary lock engaged. The fit and finish is very nice as well. Well, I am going to go play with it some more and test it out. Thanks for the input everyone!

 

[Cliff Stamp]

.... no sense of proportion.

Proportion is relationship of comparative magnitiude, which is exactly the issue here, in comparison to other knives, the Fulcrum IID cuts very poorly due to its grind, there is more to cutting ability than just sharpness.

Now you could try the arguement that it cuts well for a tactical folder, but this doesn't hold either because of extreme nature of the primary grind and stock thickness which would even be overbuilt for a 10" prybar class bowie.

...of appeals to me.

It works well as a utility tool, I carry it alongside other knives which do most cutting work. I adjusted the profile significantly to improve its cutting ability, but it still is problematic on binding material. The safetly mechanism on the lock back is nice as it prevents white knuckle releases.

After playing with the blade a little more I can kind of see what you are saying. My Al Mar SERE definitely is a better cutter and I carry it in tandem with my ER. Althought the ER did come shaving sharp, sharpness is not everything and the edge is a little thick to be as efficient at most normal cutting tasks. But the ER is just so massively built that it inspires a confidence to use it like I have never experienced with another folder. Just click the cross bolt safety over and you are ready to rock.

Like I said before, this blade will mostly be a backup defensive piece to compliment a fixed blade and a firearm, so I am not sure how much utility use it will see. But its nice to know that my arm would probably break before that lock would give away.

 

[Cliff Stamp]

Yeah I can't imagine breaking the lock itself, my main concern would be with the pivot and the lock either opening up, or the handle starting to seperate, but from the work I have done it holdsunder much more force than would commonly be applied to folders.
