I'm having some trouble with my marking knife. No matter how careful I try to be, it keeps wandering and I end up slicing into my straightedge, leaving behind those annoying curly shavings. It's frustrating because it looks so easy when I watch videos online. Can anyone share tips on how to get it right?

It’s likely all about technique. Your marking knife should have a flat side that needs to sit against the straightedge while pulling it along. Keep the knife parallel to avoid any unnecessary contact with the straightedge. Also, if you're using a plastic or acrylic straightedge, maybe consider switching to something metal—it'll hold up much better!
It sounds like you're pressing too hard! Try making a light cut first—if you need a deeper mark, go in a second time with a bit more pressure. Use a lighter touch, especially if you're working with figured wood. Also, what kind of straightedge are you using? If it's aluminum, that might be a factor in the damage you’re seeing.
