It is a good idea to have a few pairs on hand of various sizes and sharpness. For the more delicate dissections, a fine tipped pair allows for precise and controlled cuts. With the big incisions, a rounded tipped pair protects the surrounding tissue from any unwanted nicks. For cutting bone, a old pair of scissors should be placed aside or use special bone tools. Usually a pair of retired tissue cutting scissors works best when maintaining the sharpness of the blades is no longer a concern.

As you can imagine, nothing is removed from the animal without a great deal of debris, blood, and fluid coating the surface. You obviously need to rinse the tissue in order to study the structure itself.
