Do you try to limit the variety of materials you cut with a certain type of blade? For example, with scissors, one is always taught to keep paper cutting scissors separate from fabric ones. I find that paper can dull a scissor blade and render is useless to cut other materials.
I use my bullet to cut a variety of things. Common materials I use are cardboard, paper, wood, fabric and thin foil like metal. Given this, does it make sense to use a specific blade for a type/group of materials only? Will this extend blade life?
Any thoughts on this?
