I've been having difficulty finding someone who can sharpen papercutters. I work in a school and we have several papercutters that need sharpening. If you know of anyone north of boston, ma who does this service, please please please have them contact me!
I await your email!
Thanks!:)

The audience for this forum is global and I think you would do well to use the Yellow Pages for your area and look under Sharpening or similar to find a local solution.

Thanks Greg. I already did that. No one that I've called will even return my call.
I have sharpened my own by using a fine file and carefully trying to match the profile of the blade.
There is an element of risk in doing this however.
The factory has a precise angle set into the blade when new that does not have a razor like sharpness.
Considering that you work in a school if you were not to get an original grind to the sharpening, it could be too keen, possibly causing someone a deep cut if it got away from them.
What I would suggest is that you look up the company on the internet and email them about it.
If it was your own personal device I would say take a file to it but because you have no control over who uses it I would just replace them.
One thing you could try is to buy a few sheets of 320 or so grit sandpaper and cut repeated slices into it.
It may make a difference.

Hello and Welcome asky314 to the Do-It-Yourself Web Site.
Sad :( news. You're not likely to find any one or any sharpening shop willing to even attempt to sharpen a curved blade on a paper cutter. Except, maybe the manufacturer. But even then that isn't likely either...:mad:
Only method I know of and have used successfully as a vocational sharpener for the last 25 years or so, is a work shop stand mounted belt sander.
Which means doing the sharpening by hand and eye. While following the curve and holding the angle into the belt which is moving down-wards into a facing up-wards cutting edge. Not an easy task for someone whom has never done sharpening before. But it works...:thumbup:
Same or similar method can be done on a knife sharpening white stone wet grinding wheel. Once completed using either method, the cutting edge must be honed to remove burrs.
The final results, done properly or as best as possible, will produce a near perfect curve. THEN the straight edge of the paper cutter has to also be sharpened.
It's edge is angled also. Looking closely one can see an angle here also on many of the blades. A slight bevel will be seen. Same method of sharpening must be done.
Neither cutting surface is easy to sharpen. Nor cost effective. But possible, done as noted above....:thumbup:
