The cutting edge,
Amazon Verified Purchase(What is this?)
This review is from: Wenger Super Sharpener (Sports)If you own any of the Victorinox Swiss Army knives you NEED one of these.
It does exactly what it says on the tin, plastic bubble/card actually, but anyway. If your penknife has a "V" shaped cutting edge this will keep it sharp for sure.
I bought one recently for my old Champ and I tell you a few firm passes of this sharpener and the blade was as good as new. Essential tool to keep gear in good order between trips.
Although it is a bit bulky for a backpack; so I would recommend a smaller type to take-away Gerber Pocket Sharpener
However, if you have an Opinel, which you might as I do, then this sharpener will not work because the Opinel is not "V" shaped; it's got a flat cutting edge. For these I bought Gerber Diamond Knife Sharpener. This does the job on flat blades and serrated edges very nicely, and apparently darts too!
