What the AI looks for in Taping Knives

Sizes
Use about 6 inches for embedding tape, about 10 to 12 inches for finishing coats, and wider for skim coats. Wider knives feather the edges so joints disappear.
Blade steel
Choose stainless for most users. Carbon or blue steel needs to be cleaned and dried every time. Rust contaminates mud and ruins the finish.
Flex
Use more flex for finishing and less flex for embedding tape. Flex controls how thin you can feather the compound.
Handle
Choose a comfortable handle, ideally with a hammer cap. A hammer cap lets you set popped screws without switching tools.
