I think it is a good idea to have more cutter family weapons. Did you have any ideas in mind?

Here's the right link to the Cold Cutter idea page.

Also, a fire cutter would be good, since the Fang of Vog doesn't attack like a cutter at all, though it does look like one.

(Also - Attacks on frozen monsters break the ice.)

Maybe like the Vile Striker and Dread Venom Striker, but with a red/orange theme?

What if the fire version kept a dark grey color but the edges and the phantom blades would have edges similar to the Searing Edge

I suggested the Searing edge's effect because I'd love to see the beautiful storm of strobe effects when you get when combined with a cutter

A cutter should remain in a cutter shape. What Holy-Nightmare is saying is the glowing effect from the searing edge could be put onto it.

As for the suggestion itself, sure. I think cutters could fill a role that many blades don't have. Personally, I am of the idea that Wild Hunting Blade should be turned into a piercing sword, and DVS should remain as is. At that point you can try to figure out the cutters a bit more. We don't need a bunch of variations of it, however as a shadow sword, it would also work. Piercing needs another weapon in its sword category, as it has exactly one attack style. Cutters are very effective against both enemies weak to pierce, hence a piercing one would be wonderful.

From there we can look at what other kind of enemies would be weak to this weapon. Slimes are a bit too hard with this blade as a cutter revolves around attacking enemies past each other, and they attack in a full 360 degree pattern. Gremlins can be annoying with a cutter as well, however it could work against them. Constructs and undead are both slow and predictable, so a cutter is going to make quick waste of them.
That being said, logically, we should have an elemental cutter... However it would be better in terms of "spreading out damage type swords" to have it be shadow.

Bottom line I guess is we need a piercing cutter, a normal one, and some other damage type (doesn't matter which). A while back we thought about a curse/shadow one, and that was neat, however a fire/shock-elemental one would be do-able too.

Cutters are great weapons, just overshadowed by their specialized-damage counterparts.

We never talked about the shape. I'm guessing you have never had a Hot/Searing Edge. The blade is literally a laggy lightsaber and would not fit the cutter.
The first part of critiquing a suggestion is knowing what the person is talking about. I wouldn't be making a statement on the searing edge if I had no idea what they looked like.
Also the game literally gives you a hot edge as a mission reward somewhere before the snarbolax mission. If I had managed to get 3814 hours out of this game without completing that mission, then maybe you'd have a point there...

I was mentioning the effect as it is not a lightsaber affect, it is a glowing outline similar to what the gran faust and divine avengers have, except only on one side. Unless I'm reading into this wrong, that's the affect proposed, alongside its glowing aura.

I will admit I haven't set eyes on either a hot edge or a searing edge for a long time, but that's mostly because I have a 5* combuster already sitting in my inventory.
