For most dissection work I use a type of scalpel which has a permanent metal handle, onto which snap disposable blades. The blades are available in a variety of sizes and shapes for different kinds of work. The No. 11 and No. 12 blades both taper to a very slender, sharp point, and are useful for fine work. The #11 blade is straight, the #12 blade is curved. Together with fine forceps, a good dissecting microscope, and a steady hand, you can do pretty delicate work with these. Regards, Paul M.
