Didn't we just look at this, maybe my memory is faulty... Inzektor Sword-Zektkaliber.  This is an Equip Magic card, which immediately should have a game breaking effect if we're to think of using in a format with triple Mystical Space Typhoon AND Heavy Storm..but as any card vulnerable to that arsenal, we can't just immediately dismiss this card.  Appropriately, this card can only be equipped to an Inzektor Monster, and when done, said Monster gains 800 attack and defense, which is a considerable enough increase.  When face-up on the Field, and sent to the Graveyard, you can select an Inzektor from your Graveyard, and it to your Hand.  That almost, more or less, make this worth playing in the Deck.  That at least ends up being a 1-for-1, maybe potentially more.

Inzektor Sword – Zektkaliber, not to be confused with Excaliber, has a number of effects that make it a playable card in Inzektor decks. First, it increases your Inzektors by 800 attack and defense. Second, once it resolves on the field and is sent to the graveyard you get to add an Inzektor to your hand so unlike most equip cards; this card will not be a negative one.

Using Zektkaliber is easy and it can be searched with cards like Inzektor Centipede and Hidden Armory. Attach Zektkaliber to Inzektor Dragonfly or Centipede. Then use the effect of cards like Armor Blast and Inzektor Hornet to get the effects of Zektkaliber and the monster it is attached to. You could also use Scrubbed Raid to actually plus yourself while stopping your
 opponent’s attack.

We're looking at Inzektor Sword - Zektkaliber, an equip card for the Inzektors. IS-Z pumps up an Inzektor monster by 800 ATK and DEF, and when it is sent from the field to your graveyard, you can target 1 Inzektor monster in your grave and add it to your hand. The 800 bonus is pretty good, as most Inzektors are a bit on the low attack side. IS-Z's other effect is really where it's at. As you can get any Inzektor monster from your grave when it's sent from the field to the grave. There are a lot of different ways this card can be used, especially with Inzektors Ant and Hornet. Im not the biggest fan of the Inzektors archtype, but this is a good card for it, even if it is a 3 MST, 1 Storm format, you might want it destroyed.

Inzektor Sword - Zektkaliber
Equip Spell
"Equip only to an "Inzektor" monster. It gains 800 ATK and DEF. When this face-up card on the field is sent to the Graveyard: Target 1 "Inzektor" monster in your Graveyard; add that target to your hand."

An odd card for the week's theme, but what the hey?

ISZ is a great card in any deck running Inzektors, but is sadly useless elsewhere. He gives much needed power to the weak little bugs and bounces an Inzektor back to your hand from the graveyard. Sadly, if you need to draw the correct card to save you, this will be a dead draw if you don't have an Inzektor in play or your hand already. An alright card for the theme, but nothing else.

This is one of the Inzektors' three actual Equip Spell Cards, and definitely the one you will see the most of. The Zektarrow gives a 500 ATK boost and makes the opponent unable to chain to that monster's effect. Zektahawk gives a 1000 ATK boost and gives the Inzektor the "Ancient Gear" treatment to make Mirror Force and Dimensional Prison unresponsive to it.

The Zektkaliber has a respectable 800 ATK increase and a negligibly equivalent boost for DEF. This is usually only important for pushing that extra 800 damage in a direct attack spree; other important targets are giving Centipede or Hopper enough juice to slaughter Evolzar Dolkka without the need of Giga-Mantis. The real gist, as always, comes in the secondary effect. Unlike the Zektarrow or Zektahawk, Zektkaliber gets its effect off of getting destroyed, and once it does, it's a costless Monster Reincarnation. This is not bad at all if you need to recycle Centipedes or Dragonflies, perhaps put a Giga-Mantis back in hand. It's also useful in that it is not prone to losing advantage at the hands of MST or Heavy Storm. In fact, you might even destroy it yourself using Hornet.

But then...why not just use Giga-Mantis? Giga-Mantis can equip himself onto a monster all the same, gives a much more considerable ATK boost, and, when destroyed, outright summons a monster to the field.

Zektkaliber's gist is that all it has to do is to be destroyed whiilst faceup (it would be better if it was just plain sent from the field to the Graveyard, but I'm fooling myself if I think Inzektors needed to be any more powerful than they are already). Giga-Mantis requires that the monster he was equipped to be still alive. That is to say, if the monster with Zektkaliber on it gets used up for Xyz or even released to summon Giga-Mantis, you still get the effect off the Sword. Furthermore, you can only use one Giga-Mantis per turn, so you can load up a bunch of Inzektor Swords on, say, a Dragonfly, then use it up for an Xyz and substantially refresh your Hand. These are extremely complicated plays that give Inzektors their most destructive force; it is also very easy for an inexperienced player to badly play their cards in the wrong order, but that should not be a factor in interpreting the card itself.
The biggest reason why to use Inzektor Sword over United We Stand in a Deck that swarms so effortlessly is because Sword replenishes itself easily and appreciatably. Also, like Giga-Mantis, Inzektor Sword's destruction (if you shatter it with Hornet) will give you a summon off Dragonfly or a search with Centipede (although it concerns me that if you do it with Centipede, you still only get one Normal Summon per turn, but you can always search a card like Giga-Mantis or another Sword that doesn't require a Normal Summon).

Oh yeah, and what many people forget is that Inzektor Centipede can search any Inzektor card, regardless of under 1500 ATK or not or under Level 4; it doesn't even have to be a monster. So yeah, Centipede can grab Spell Cards.
I see Inzektor Sword used a lot less than Giga-Mantis, and I prefer Giga-Mantis' direct summon over Sword's restoration to the Hand, as that doesn't use up your Normal Summon for the turn. However. I only have experience in battling Inzektors; not using them. I have also interviewed experienced Inzektors Duelists and they have given me the consensus I need to mark this card extremely high.

Traditional: 3/5 (if anything, it'll give some protection against CED, and to a further extent, Yata-Garasu)

Advanced: 4.5/5 (it's not splashable, but it gives a great deal of power to an already devastating archetype, and that in itself makes it very, very potent)
Aesthetics: 3/5 Lol, Inzektor Exa-Beetle. I guess it goes without saying this is based off of Kamen Rider Gatack's weapon?
