Hex keys: Bondhus Balldriver L-Wrench Double Pack (1.5-10mm) and (0.050-3/8-Inch) $14.01

Bondhus is one of the few hex key manufacturers at this point who makes hex keys from steel that doesn’t get chewed up. Nothing wrong with the HF $5 version of this, especially with how fast they tend to get lost, but these could easily last 3x as long in my experience.
CCC lists as best price.
