Smaller vs. bigger taping knives
|
|
|
|
|
Smaller
With smaller (3-6 inch) knives you have more control and the ability to get into smaller crevices. |

Smaller knives are generally for laying tape, filling gaps, applying joint compound to seams, and decorative work.
You can use a bit more force with a smaller knife to really make sure you fill those screwholes and seams.
If it looks a little scruffy don’t worry you’ll be using the larger knife to neaten it up! |

Bigger
With larger knives you won’t be using as much force but you will be able to cover a greater area with more delicate strokes.
Larger knives are better for feathering (blending in) edges and spreading. |

Both?
Make sure you have at least a small and a large taping knife, as you’ll need them for the different processes of drywalling.
It is also advised to have a joint compound tub for ease of access. |

Most taping knife handles are designed for a larger hand.
Decorators with smaller hands may find extended jobs become uncomfortable, so choose a knife that you can grip comfortably.
Remember, the more secure your grip, the more control you will have over your blade! |
