Hard case, tough core. The general-purpose choice, and the right one for long thin pins or any tool with side load or slight misalignment — the soft core lets the pin bend rather than snap.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/through-hardened-ejector-pins-pack-of-10\"\u003eThrough-hardened\u003c\/a\u003e.
