d. Putty Knives. Among the many different putty knife styles available (Figure 3-7), there are
those with short, stiff blades; long, flexible blades; wide blades, and narrow blades. The original
purpose of putty knives was to gaze window panes into window frames, but they are often used to
scrape old paint surfaces and apply joint cement to sheetrock walls. Putty knives seldom need
sharpening, but they should be stored in a manner to prevent damage to the blades.
e. . Cold Chisels. Cold chisels (Figure 3-8) are used to chip paint or scale from metal surfaces,
and the chisels are available in different widths and lengths. Chisels are sharpened by grinding their
heads on a grinding wheel to restore the bevel, which is usually at a 60- to 70-degree angle.
Occasionally, you may need to remove the burrs from the heads if the heads have mushroomed.
