The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
FIrst time :
The first time he received this augmentation was in Wolverine #126 (by Chris Claremont and Leinil Francis Yu)
Captured by Apocalypse along with Wolverine, Sabretooth has adamantium grafted onto his skeleton and claws. This was done to make him even more powerful, given the fact that he was then under the mental control of Apocalypse. Unfortunately for Sabretooth, the upgrades didn't last. Wolverine beat him in combat, and Apocalypse subsequently stripped the adamantium from Sabretooth's skeleton. He would then put it back onto Wolverine's skeleton, as the hero had still been using bone claws following a nearly fatal encounter with Magneto years before.
Now Days :
Shortly after this experience, Sabretooth would gain adamantium claws once again by way of a new version of the Weapon X Program during Frank Tiere and Sean Chen's 2001 run on Wolverine... Sabretooth was believed to have retained the metal bones and claws he gained from Weapon X even after the Scarlet Witch's reality altering events in House of M, but the depiction of this has been inconsistent throughout the years.
And obviously... Stated Saberooth fangs and natural claws are also Adamantium, as well four retractable claws on each arm.
After the Marvel Team Up comic that first introduce Sabertooth, we see Sabertooth undergo the same Adamantium process as Wolverine, getting four claws instead of three. Being enhanced.
Sabertooth again stated to undergone the same Adamantium process as Wolverine. The same experiments.
