It is true that there are many different blades to choose from but here is my take on them. Blade retailers usually charge the same unit price no matter which size from the smallest to the largest size of any particular blade type. The smaller the blade the easier they flex, bend, and break so I tend to use the smallest sizes only when the project demands them. I think you will find you can cut, as I did, some quite fine detail without having to resort to the smallest blades. As you try different blades you will probably finally settle into just a few that you will use most of the time. Good Luck
