Introduction: Sharpen a Knife, the Geeky Way.
I just found that old amd CPUs have a large ceramic plate that the I/O pins stick out from and since ceramic is a much more durable substance than steel we can actually use CPUs to sharpen knives :D
1. An AMD CPU
2. a dull knife.
3. 2-5 minutes.
Step 2: Sharpening Process.
This part can take some practice but it's really easy once you get the hang of it.
Since I only had one hand to do this with my angle is off try to keep the sharpener at a 35* -45* angle to the knife.
Make sure you're always scraping toward the tip of the knife ,and while you do that always slide the sharpener toward the direction of the knife blade.
Pictures 3 and 4 are sharpening the tip it's mostly the same but all you need to do is rotate your wrist. If your blade is tanto style you can use the same method as sharpening the flat part of the blade.
Just make sure you don't scrape the entire blade in one swipe do one section at a time.
After you swipe both parts of the blade 3-5 times flip the blade and do the other side. I'd recommend starting with about 5 at first and work your way down to 2 per side. 5 top 5 bottom 4 top 4 bottom 3 top and so on.
Step 3: Is It Sharp Yet?
Paper test always works good put some paper on your desk or whatever and see how much pressure it takes to cut through while slicing.
Try shaving with it? Don't have facial hair well try cutting some of your sisters hair while she's asleep shouldn't take much to get through if it does then you need to try again... well lets just say better idea to not cut ur sisters hair...
