A magically-enchanted wheel that was a Mother's Day gift.

Catherine Wheel

There aren't many mechanical things present on the Olympus Wheel, other than handles to hold onto with and a corkscrew lock. The corkscrew lock lets the outer wheel spin into place to open it up further. This activates the enchantments found within.

Cherry wood, steel bolt and accents. Some brass around the center of the wheel.

~90 lbs

Two wheels held next to each other, the corkscrew lock opens the wheel up. Both wheels are shaped like cartwheels, but they are made of cherry wood. Dark, polished, and sanded to a smooth finish.
There are metal accents with knobs for some extra tenderizing power, but they are mostly there for decoration.

Wheels themselves are 3' in diameter, and they are 7" wide.

Can be "revved" to apply a magical effect. The effect is a magical force that increases damage and can launch targets farther.

Can be recalled to the wielder's hand at will.

The Olympus Wheel was a gift for Guinevere from Yama. He bought the weapon itself from an auction surrounding the memorabilia of a famous hunter. The weapon had no magic to begin with, but Yama had a friend modify it after it was cleaned up.
At first, Guinevere had no idea what to make of the weapon, but after her son demonstrated it to her, she immediately set to training with it. Fighting with this weapon mostly deals with slamming it into enemies, and "revving" it to apply the magical force effect on it. This force increases damage and can launch enemies further. Guinevere accidentally smashed a wall that way and nearly caused a cave-in. She would train outside from then on.
