There is lots of information out there on the basic use of a swivel knife. There are only a few basic moves and rules in the proper use of a swivel knife. Skill is the factor that determines the quality of your cuts, and skills are honed to perfection only by practice and repetition. Learn the basics, practice a lot and try to learn from each project to make the next project better. With enough practice and time it will become second nature to you, but it will never happen if you don't put in the work. I have used a swivel knife for 45 years, and I still see room for improvement in my work. Good luck.
