Trabecular meshwork of a pig’s eye
The trabecular meshwork of the eye acts as a filter located behind the cornea. Behind the cornea is fluid to protect the eye from dust, wind, and other disturbances. We need this fluid for proper eye function, and it needs to be properly drained to prevent unwanted build-up. The trabecular meshwork makes this possible. When it cannot function properly, a disease called glaucoma results. The vision loss associated with glaucoma occurs when the fluid pressure in the cornea causes damage to the optic nerve, the nerve responsible for sending “sight” messages to the brain.

Egyptian ceremonial Saw in the Shape of a Ma’at-feather, ca. 1353-1336 B.C.E.
What was Ma’at?
A difficult concept to summarize, but I would describe it as the Egyptian concept of balance, truth, law, order, justice, and morality; it was also personified as a goddess -identifiable by the feather she always wears on her head.
Here are a few more examples of Ma’at being represented elsewhere in Egyptian art:
- On The Papyrus of Ani showing the ”Weighing of the Heart.” Note the Ma’at feather on the right scale
- Relief of Ma’at shown in the Temple of Edfu, Egypt.
- Scarab with Script Sign Combination at the Walters Art Museum.
It was the duty of all Egyptians to live in accordance with Ma’at. Only if they did so could they join the society of the dead when they died. In the final judgement that every Egyptian (even the king) had to pass through, the heart of the deceased was weighed against a feather to determine if his or her actions in life (symbolized by the heart) were in balance with Ma’at (the feather).
Unlike the final trail of Christian tradition, this was not a religious judgement but a social one: people who had been disruptive elements in the society of the living could hardly expect to be welcomed by members of the blessed society of the dead.

The shape of the shown saw suggestions that it was used for ceremonial purposes, possibly preparing meat for sacrifice to a god. Artifact courtesy & currently located at the Brooklyn Museum, photo via their online collections.

Practice Sword (Iaitō) - Inazuma
Iaito (居合刀) is a modern metal practice sword, without a cutting edge, used primarily for practicing iaido. This sword, called Inazuma, its name meaning “a flash of lightning”, is a concept that every student of iai should be aiming for in their techniques.
This model is specifically targeted toward iaido kata with a special focus on performance based customisation - Inazuma comes with a huge choice of options at no extra cost to make your iaito totally individual.
It is forged and folded lightweight 1095 blade is constructed to be marginally thinner and therefore an ideal weight for iaido practice - not as heavy as a traditional shinken yet not as light as its zinc alloy counterpart, making kata easy and controlled.
