I am very new to leather crafting and the one thing I cant seem to get down is the swivel knife, every time i use it it just looks like it is making scratches on the leather(i am using thinner leather) and i have cased it before hand. Also could it be the knife itself? Does how think or thin the knife is have a difference on outcome? any tips or tricks would be greatly apprectiated!

Does how thick my leather is make a difference on outcome when using a swivel knife?
