I've noticed some marking knives come with carbide blades, and I'm really curious about their longevity. How much longer do these edges actually last compared to standard steel? Also, how do you sharpen them when they do get dull? Are there any downsides to using carbide besides the cost?

I’ve had a similar experience with some old tools. I have a Czech Edge awl that's carbide, and it’s delicate. If it’s too pointy, it chips easily. A well-maintained steel knife is more practical for marking. Plus, if you drop tools like I tend to do, a steel knife is much more forgiving!
