No, karambits are not hard to sharpen. In fact, they can be quite easy to sharpen if you have the right tools and know-how. Here are a few tips on how to sharpen your karambit: 1. First, find a sharpening stone that is appropriate for the type of steel your karambit is made from. If you're not sure, ask a professional or do some research to make sure you get the right stone. 2. Next, set your karambit at the correct angle on the sharpening stone. For most karambit, this will be around 22 degrees. 3. Start with light strokes and gradually increase pressure as you go along. Work evenly on both sides of the blade until it is nice and sharp! 4. Finally, use a honing rod or strop to really fine-tune the edge and remove any burrs that may have been left behind during sharpening.
