You need large, sharp scissors for cutting out. Special cutting-out scissors are designed so that the underneath blade will lie flat on your cutting surface. Little pointed scissors are best for all the small, detailed cuts (like snipping off threads) for which the larger scissors are too clumsy. Then you need paper scissors for cutting out the paper pattern pieces, because that would blunt your good cutting-out scissors. A special slashing knife is practical but not absolutely necessary for slashing buttonholes or pocket openings. Use zigzag shears for cutting out lining or a non-fraying fabric, so you don’t have to neaten/finish the raw edges. The blades should be really sharp for cutting out fabrics. A small point is ideal for trimming off threads. Pinking shears provides a trendy zigzag effect on non-fraying fabric edges.
