I have just traded for a Pentagon Elite II, which I plan to carry as a back up weapon in situations where I can't easily conceal a large fixed blade. I have trained extensively with double edged blades and want the PE II to be as effective as possible. I was wondering about having the false edge sharpened. Can this be done on this knife to match the sharp edge? Who does good work in this area?
 
doing that to a folder is not a good idea imo

BUT

if you MUST do it, just use a course diamond stone and then move to a finer one for the finishing work.
 
In some places that would make it a dagger instead of knife and would be illegal !!
 
forget the legality, id be worried about the back of the blade nudering me if i set down wrong.

Not to mention your pants being cut, and your hand when you reach in for your money clip, not a good idea at all.
 
If it has a false edge, then it's already sharp. Keep it sharp just like you would any other knife.

What you probably have is an unsharpened suggestion of an edge on the spine of your blade. That is called a "swedge." A false edge is not "false" because it is not sharp. A false edge is called an edge because it is sharp. It's false because it doesn't run the full length of the blade.
 
MOD Mark I and II has false edge hidden in the handle, it is OK to haver it sharp.

Thanks, Vassili.
 
i have seen a gerber applegate folder that had the top edge sharpened, IIRC it came that way, i guess it worked ok, if the PE has an exposed spine it wont work though, the applegate is one of only a few that this would work on, IIRC a BM spike would, other than that i cant even think of any others right now.

of course its illegal most places.
 
Hopefully you got your false edge sharpened by now, and ignored all of the un-educated untrained opinions expressed on this thread! The edge is concealed on your PE II and it was made to be user sharpened.
 
cbrzrule, welcome to Bladeforums.

Many of "the un-educated untrained opinions expressed on this thread" came from experienced knife knuts, at least one of whom put in a career in law enforcement. You might consider waiting until you know some of us before deciding you know more than some of us.

Whether or not the knife can be carried safely with the swedge sharpened, it still is illegal in many jurisdictions. Since we don't know where the original poster is located, nor his age, or possible likelihood of being stopped by law enforcement, it's worth mentioning the legalities.

By the way, this thread you're responding to dates from April of 2005, so it's unlikely the original poster is still monitoring it, especially since he never responded after starting the it.
 
that would be a dumb idea on a folder

, but if you must you can regrind it yourself with some sweat elbow grease and about 4 coarse sharpening stones from WalMart.....

best is to bring it to a sharpening-shop though. they'll do a good job on it for a mere $5, if they're good and honest that is

on the other hand....it's still stupid. it's a FOLDER! :rolleyes:

It's called a "swedge" ..... I did not know that ... What is a "zero edge" ... ?
WOOK.
 
A zero edge is a primary bevel with no secondary bevel to strengthen it. The grind on both sides of the blade continues to the very edge, which will be quite sharp. But it will also chip, roll, or otherwise degrade more easily than if it has a secondary bevel which is slightly more obtuse, but too short to seriously hamper sharpness.
 
The spine of the blade sticks out beyond the handle scales and would be very dangerous if sharpened. Here is a photo that shows this.

What do you call an edge like the one on the SOG Pentagon folders that runs the whole length of the blade and looks like a sharpened edge, but isn't?
 
An unsharpened back edge. :D

Another problem with false edges and long swedges that I've found with fixed and folders is that I often push an index finger or thumb far up the blade for control, and a narrow back edge, even unhsarpened, is uncomfortable and unstable since I can't really put pressure on it.
 
Here is a defintion of a false edge taken from a glossary on the ebladestore.com website.

Widely used on military and combat fighting knives, a false edge blade is an additional bevel on the back of the blade enhancing the blade's point. This edge can be sharpened or not. The false edge can also be used for heavier cutting that might be damaging to the cutting edge.

The defintion below comes from the knife-guide.com website.

Swedge (non-sharpened): Also called a false edge, it is a ground edge on the back of the blade's spine, that is chamfered, or non-sharpened. It removes weight from the blade and can change the blade's balance and penetration performance and appearance.

There seems to be some confusion as to the definition of swedge and false edge.

Sure does. Personally, I like Chuck's distinction, that a swedge is unsharpened, at whatever length, and a false edge is a partially sharpened back of blade, like a sharpened bowie clip.

Taking my own frequent advice, I refer to A.G.Russell's Knife Encyclopedia:

False Edge
A sharpened area on the back of the point of some large knives.

Swedge
A bevel grind on the edge of the back of a blade. If it were sharp it would not be a swedge but would be a False Edge.
