Any tips for removing or filling in a 5-6mm long knife wall slice? It’s on a part of the wood that it will be seen. I’ve considered using water and hot iron but the wood isn’t so much depressed as fibres sliced.
EDIT: Perhaps a recommendation for a wood filler?
"Sawdust? I think you'll find that's man-glitter."
This is something that I am fairly sure is common as far as woodfillers go, but for me taking wood glue and filling the gap almost to the top and then filling the rest with dust from sanding the wood results in a decent color match, and if you have enough dust at the top of the gap you can still sand it smooth so long as you do not sand too far and reveal the ugly orange dried glue underneath.
