It takes practice to know when your tools need sharpening. But for both hand and power cutting tools, the warning signs are similar: It takes more effort to cut wood and to control the tool while you're doing it; the results are below par, with telltale signs such as burning, a dull surface, or tearout; and the edge of the blade itself shows signs of wear. Several of Fine Woodworking's contributing editors weigh in with advice on how they determine it's time to stop cutting wood and start sharpening tools.
