Similar to the edge, material and shape are two criteria to consider when choosing the right handle of your knife. If you want a classic look for your knife, choose a bone, wood, or plastic handle that resembles the material of either of those. If you prefer something sleek and modern, go with a clean metal handle. If you are after something tactical, a rubber or composite handle will be the best option. As for the shape, the best handle must satisfy user comfort and carrying preference. If you have large hands or usually wear gloves, the larger the handle, the better. If a compact size is what matters, choose a slim handle.
