All I can say to you, is you aren't going to get a blade with sandpaper... Bring it to a knife sharpening shop and get it sharpened there. If you're too young (just judging by grammar), get your parents to bring it to a shop.

If you live in the country and you are a billion miles away from a town, then you should own a farm, am I right? Every farm I've been to has a belt sander for some tool or other...

To the question "Is there a faster method?"; the answer is either "A grinding wheel" or "No." (Sorry about that)

(I've never done it myself, but) concrete, maybe followed by the unglazed "foot" on the bottom of a dinner plate, is probably your best option. Take it slow and easy, remeberig that it'll be a lot slower if yu get hasty and mar what edge you've already formed.

Try to view it as an exercise in developing methodical patience, sort of like a zen thing. Concentrate on the process and try not to get over-eager for the result. Listen to your fave music, with headphones if you've got them, or watch TV.

A good knife blade honed by hand is a work of craftmanship and steady, careful labor; and has great value because of that.

Good luck! :)

+1.

Sharpening involves removing metal to create the thin edge, preferably without letting the metal heat up enough to change its temper. Abrasives -- a whetstone, for example, or the mechanized equivalent which is a grinding wheel -- are how you do that.

It is possible to resharpen something which is already correctly shaped using sandpaper -- though a much finer grit than 60! -- and in fact there are commercial sharpening systems based on this. Essentially, that acts as a whetstone with replaceable grinding surface. But trying to shape the original edge that way will be just as slow as you fear.

Combining that idea with the grinding wheel suggestion... it might be possible to use a belt sander. I seem to remember hearing that some amateur knife makers do use motorized sanding belts to do some initial shaping of blades. I have no idea what grits would be suitable for the initial shaping. Of course, to get a usefully sharpened edge you're going to need finer abrasives than the concrete and 60-grit you've mentioned, but maybe a course grit would suffice for initial shaping.

Doing it without *some* mechanical assistance, even if that's driven by foot pedals or a crank, seems to me like it's going to take longer than _my_ patience would last. But if you're being entertained by the attempt, go for it...

I would probably go for the file idea if it actually can file away the scissor blade, they next choice would be concrete (yeah prison shank style) then 240 grit paper. Other than that I would look around your place. If you live a bazillion miles away from everything and have lived there for a while I would imagine there would be some sort of item that would help you out. Do you chop wood at home? how does the axe stay sharp?

You need to find a metal file. They are cheap and lots of people have them in their tool boxes. It's slow to file that much metal but it will do manually what a grinding wheel would do.

Probably not. You need a file that is made out of a material harder than the metal you're trying to grind away. Files used for fingernails or calluses are extremely unlikely to be any harder than they must be for those soft materials. Cheap tools are rarely good; good tools are even more rarely cheap (unless you're lucky enough to find a good deal on used tools.)

. I've seen some reasonably priced diamond files. But they are usually very fine (~240 grit) so they wouldn't remove metal very fast.

This link will tell you how knife cuts. Read it throughly and you'll understand why using a scissor blade just won't work. It also describes how to grind so go ahead , read it, and do it anyway :D

A hard flat stone will eventually wear it down. Wet the stone and rub the edge at an angle. A metal file will be faster though. Knowing how to use a file is important also. After you're done filing it down, you'll have an edge but it won't be sharp. Take a leather belt or heavy leather glove and use it as a strop. You draw the knife away from the edge on the face of the leather, flipping it on each draw. Once you've stropped it, it will be sharp but not hard. You'll then have to heat treat it.

Google some knifemaking websites. There are lots of them.
