Abstract: The single most difficult physical skill involved in wood identification is producing a smoothly prepared surface for observing anatomical features. This skill must be practiced patiently; it takes time to become proficient at this task. Producing a cleanly cut surface is also the only appreciably dangerous aspect of wood identification with a hand lens; the tools used to cut the wood are necessarily sharp, and injuries from minor cuts to major lacerations can result from carelessness, fatigue, or poor technique. Safety must always be the first priority, followed closely by the secondary importance of making a serviceable cut of the wood. Because this skill is both necessary and inherently dangerous, patience and prudence must be exercised while learning. After nearly 16 years of teaching wood identification, I have learned that beginners generally do not follow the advice of their instructors and instead try to move ahead without taking sufficient safety precautions. In that same period of 16 years, I have also never cut myself deeply enough for blood to flow freely; I have only required a few small adhesive bandages in my professional career, specifically because I have followed the suggestions and used the techniques outlined below. Before trying to cut a specimen of wood with these techniques, please read and understand the entire chapter.
