If you actually ever dwelled into the issue, you'd understand most of those cuts were clean. Cross guard doesn't help shit, if your hand is hit at 90 degree angle.

Secondly, due to the nature of lightsabers it was impossible for the blade to "slide" down for a hilt to make sense. Why? Because magnetic fields stop lightsaber on the spot and lightsabers themselves use magnetic fields to maintain the blade, so when two collide, you can only pull them away, not slide them aganist each other like normal swords.

Thirdly, early versions of lightsabers were ceremonial blades, that require a huge battery strapped behind Jedi's back to work merely as a flash light for a moment, due to energy loses and overheating. Later iterations were closed circuits with build-in energy cells that only lost energy when actively cutting something, hence why those "modern" models lasted for years.

Kylo's basically has two blades. One "proper" and second "prototype", that's entirely lost energy.

The fact his lightsaber didn't run out of power while merely fighting Rei, makes it one of the biggest jokes in Star Wars.
