The Yang Metal Day Master (Geng 庚) is pictured as an axe or a blade. It is the stem of edges: decisiveness, standards, and the willingness to cut what no longer serves.
The tradition treats Geng as a reforming force — not cruel, but unsentimental about what needs to change.

| Geng 庚 | Yang Metal | An axe or blade | Decisiveness, standards and reform |
A blade is defined by its edge, and so is Geng. In practice this shows up as decisiveness: a tendency to see the decision and make it, to cut through ambiguity rather than sit in it. Where others deliberate, Geng tends to act.
The image also carries standards. A blade that is not sharp is not a blade, which is why Geng is often associated with quality, correctness and holding a line.
The same edge that cuts through problems can cut people. Geng's directness is a strength in a crisis and a liability in a delicate room; the tradition warns about the blade used where a word would do.
The useful distinction is between being decisive and being harsh. Both are fast; only one keeps the trust that makes the decision stick.
Geng tends to care about how things are done, not only whether they work. This shows up as process orientation: systems, standards, corrections, the insistence that a thing be done properly.
This is the energy that reforms a broken process. It is also the energy that can over-correct a working one, so Geng benefits from knowing when "good enough" is genuinely enough.
Geng tends to thrive where decisions must be made and standards must be held: turnaround work, quality, security, engineering, crisis roles, anything that rewards a clean cut.
The reflection prompt: is this a moment that needs a blade, or one that needs a hand?
Think of a security engineer who closes a vulnerability the same hour it is found. No committee, no delay, no incident. That is a Geng pattern: the edge used exactly when it is needed.
Tradition pairs Geng with Fire to refine the metal and Water to temper it. Unrefined, the blade is brittle; untempered, it is harsh.

Not inherently. Geng is described as decisive; the same edge can cut a problem or a person, and the chart context matters.
Bluntness — decisiveness applied where sensitivity was actually required.
