Abstract
A blade head assembly for a hand-held hair cutting appliance includes a blade clamping device urging a cutting edge margin of a second blade in sliding engagement with a cutting edge margin of a first blade. The blade clamping device includes a clamping head operable for pivoting generally toward and generally away from the second blade about a pivot axis. The clamping head is resiliently biased generally toward the second cutting blade about the pivot axis into sliding engagement with the second blade. The second blade is slidable relative to the clamping head during reciprocating movement of the second blade relative to the first blade.
