'Joanne',

The greater the space between the teeth the larger the tips\branches
which can be cut.

For instance, if you had a spacing between the teeth of 30mm then,
whether the twigs\branches be thin or as thick as your finger, there
would be ample room for them to pass between the cutter-blade teeth.

It would appear that 14mm will meet your present requirements.

Emrys Davies.

Could someone explain "tooth spacing" on hedge trimmers? I'm choosing
between two trimmers; one has tooth spacing of 23mm and the other
14mm. I
want it simply for the twice-yearly trimming of the soft tips from a
conifer
hedge, nothing heavy duty.

Thanks.
