Final answer:
Taper 32 shears have the least amount of spacing between teeth, with a higher number of teeth compared to taper 8 and taper 16 shears.
Step-by-step explanation:
The shears with the least amount of spacing between the teeth would be the taper 32 shears. In hairdressing, the term 'taper' followed by a number usually indicates the number of teeth on the shears. A higher number means more teeth and therefore less space between each tooth. Thus, taper 8 shears have fewer teeth with more spacing, taper 16 shears have more teeth with somewhat less spacing, and the taper 32 shears have the most teeth with the least spacing. Channeling shears are a different type of shears used for creating channels within the hair and are not typically categorized by the number of teeth in relation to spacing.
