Dual-phase Splitsaber with Shoto and Crossguard modes.
Cal got himself one of the most practical sabers in Star Wars.

Forgot the ones only seen in the Phineas and Ferb star wars crossover episode

Crossguard lightsabers would be functionally better if the cross guard was made of a lightsaber resistant material instead of plasma. That way it can protect the user's hand without endangering further hence defeating its purpose

Edit: *sigh*… yes like beskar. You don’t need to mention it

13:12 Well, if we’re going there I’d say my favorite lightsaber is the one from the Phineas & Ferb Star Wars episode where they heavily mod their lightsabers to an entertaining degree.

By far my favorite Saber design was Asajj Ventress' curved hilt that joined into a Saber staff

One variant wasn't mentioned: the Long-handle Lightsaber. Meant to resemble long-handle swords like the nagamaki, pudao, and the swordstaff of different ancient cultures, this lightsaber variant provides more leverage and handling than a standard lightsaber. It can be used both as a sword and staff during combat. Darth Chratis, Darth Nihl, and Zao are among those who have used this variant.
Hell, I have mine in a yellow blade made by Ultrasabers and brought it to a ComiCon in Indy earlier this year, and I love it! The people at Ultrasabers were there and were kind enough to upgrade my baby with newer parts!

Golden rays of the glorious sunshine
Sending down such a blood-red light

light pike all day, historically, long pointy stick win, and being able to mod the shaft so you can utelize the shorter blade for CQC would be an added bonus

I’d use a standard double blade lightsaber, with a yellow crystal. Simple, but effective

Ezra should have kept the hybrid blaster-saber.  Yes, he had grown as a Jedi and didn’t need the extra trick to keep up, but he was also not in a position where he should be turning down any advantage.  Also, it lets him stun people, which frankly is a rare option for lightsabers to have.

The gauntlet one that was gonna be wielded by plo would have been awesome to see

You forgot the war dragon rider lightsaber. It's a saberstaff, but has a small blade in between the ends, for a total of three blades.

I think the coolest lightsaber variant is the light saber nunchaku, which was wielded by Ventress in the DLC for the classic Star Wars: Battlefront 2. However, I would choose the hinged double-bladed lightsaber like the Temple Guards.

I’m interested in hearing more about things such as vibroblades, in relation to how they differ & resemble a standard saber. Also, more about whips. This was interesting and at parts, funny. (That bit at the end with the Lego Maul octosaber!) Thank you

Split saber, green crystal. I love the idea of Jedi consulars and the split saber is just so efficient.

The telescoping lightsaber pike from the Knights of the Eternal Throne trailer is the variant that I'd love to see brought into canon. It can be used as a normal lightsaber, or you can extend the handle for extra reach.

I really liked the blade used by the guy in the star wars visions episode where he couldn't retract the blade

I’d love an axe or warhammer variant. Like a saber that could be supercharged from the force from a Jedi’s last stand. That’d be cool

I'd definitely use Cal Kestis's saber, its just got so many options

I would use a double bladed lightsaber, with the bottom saber being a dual-phase shoto. It'd mainly be used single-bladed as a standard saber with a somewhat longer hilt as to keep the second hidden. The shoto would detach and as to be used as two separate sabers.

Only reason I got this idea is due to a Darth Vader toy from when I was kid that featured a huge hilt with a small dagger like saber that could be removed or added to the bottom.
