How to spot it

Find two planets linked by a sesquiquadrate (135°). Involved here: Saturn, Neptune, and Venus.
Both should aspect a third apex by square or sesquiquadrate.
Turn minor aspects on — Thor's hammer will not show if only majors are drawn.
In this example the points sit in houses 1, 4, 8 — map yours with Placidus cusps, not whole-sign counts.

What it means

Thor's hammer is traditionally read as irritant energy aimed at an apex, built from minor aspects (sesquiquadrates) rather than a classic T-square. Because minors are easy to miss, the figure is often under-counted in casual software. The apex house in Placidus names where the friction may localise. Do not inflate it into mythic violence; treat it as a specialised tense wedge and weigh it against major aspects first.

Variations

Common misreadings

If you only see majors, you will miss Thor's hammer — it depends on sesquiquadrates.
It is not simply 'a harsh yod'. Different aspects, different figure.
