When chiseling it is well to stand so as to look along the line being cut.

Incline the chisel toward you, and use the near part of the cutting edge for a guide and the farther corner for cutting, pushing the handle both down and forward at the same time, Fig.73.Or, by pushing the chisel sidewise with the thumb of the left hand at the same time that the right hand pushes it downward, the effective sliding cut is obtained.
[Illustration: Fig.73.Chiseling End Wood.] [Illustration: Fig.74.Paring a Corner Round.] [Illustration: Fig.75.Right and Wrong Ways of Perpendicular Chiseling.] End chiseling requires considerable force and therefore only thin shavings should be cut off at a time.

Or the mallet may be used with caution.

In order to leave a smooth surface the chisel must be very sharp.

Even then the lower arris (corner) is likely to be splintered off.
