Introduction: SHARPEN Your X-acto Knife Blades DON’T Replace Them It’s Cheaper and Faster
Just imagine, if you could sharpen your X-Acto knives instead of replacing them. Think of the money you save. I’ve been using an X-Acto knife for years and years. At this point I can sharpen the blade faster than I can change it out. Several swipes on the sharpening stone or piece of sandpaper will give you a razor sharp finish on your blade. Just keep the stone right next to you while you’re working and if you feel it starting lose its sharpness then sweep across the stone, and keep going. This technique has been very valuable to me I hope it is just as valuable to you.
Step 1: Sharpen
Sharping your X-acto knife blades is very easy to do, let me show you how. Put the blade flat with the angle of the edge and run it back and forth. Just repeat this until your blade is sharp. Yep that's all there is to it! Hope this helps you out of a pinch!

You're going the wrong way. Push with the cutting edge facing away from you. You're doing it backwards. And you need to lubricate the stone.

The pointy part is gone though. I need that part because I cut paper with it. I was looking for some ways to fix this problem, I am really short on money and can't buy a bunch of those blades. Any help woud be appreciated.

If you can't buy a bunch of those blades you probably can't buy a sharpening stone either. A 100 pack of blades is $20 and a cheap sharpening stone is $20, plus the cost of whatever oil you decide to use. Regular mineral oil is usually cheapest. They do have stones that use water but thatll just corrode your blade faster and still neither will give you the point back. For that you'd need at a decent dremel or at the minimum a good power drill with a griding bit.

Something I like to do, especially in the earlier days of using the blades, is to lower the handle. Instead of keeping the blade upright, where the tip more "drags" the paper rather than cutting, if you place your hand closer to the back and use little downward force, the blade will cut easier. You'll need a few more passes, but I break less tips that way.

I use jeweler's rouge and it prolongs the blades as well.....I have a few of the disc blades that go to micro finger cutters and they are EXPENSIVE to replace and being round the jeweler's rouge is awkward so I used a mandrel for cutting discs and used my dremel to sharpen them on my stone......worked wonderfully

What grit of stone do you use?
