Sure! The lower one is an iaito. A training sword mostly used to practice fast-draw techniques. This one is steel, whereas most are aluminum, so has the heft and balance of a real sword.
The upper one is a real katana, also known as a shinken. It is of modern manufacture, and made in a Chinese forge, but to the same specifications as the original Japanese process. It is layer-forged and clay-tempered, and very sharp.
I run through the 12 basic sword forms every morning.
