I've been a technical manager for many years, and before that a technical specialist.
I continue to manage technical teams, so you might say that I am a technical manager. However, 'technical' is now the least demanded of my skills. Having a technical background – where the bulk of my skill was previously focused – makes some of the roles I must now fulfil pretty challenging and mentally demanding, but in very different ways than when addressing technical needs or problems. Does this make me less of a specialist, and more of a generalist?
