I hate to break it to you, but you really can't do much luthier work without learning to sharpen tools.
You just gotta set aside a few hours, get on YouTube, and find a method that works for you.
You don't need a $200 Japanese whetstone to start, truly. Sandpaper will do if nothing else. Here I've got an old file and an old oil stone.
It took me a few tries, but I think I got the hang of it now!
