Yes, you can sharpen a Microtech. However, it is important to note that sharpening a Microtech will void the warranty. With that said, here are the steps to sharpen your knife:
1. First, you'll want to find a sharpening stone. If you don't have one, any medium grit stone will work fine.
2. Next, wet the stone with water and then place your Microtech on the stone at a 20-degree angle.
3. Using light pressure, move the blade back and forth across the stone until you've achieved a nice edge.
4. Finally, rinse off your knife and test it out on something like paper or cardboard to make sure it's as sharp as you want it to be!
