The weapons range in quality, costs different amount of Forge Tokens, with some artifacts raising attributes more than others. They also use different amounts of materials to upgrade. The artifact weapons are:

Upgrading Artifact Weapon Components in King's Throne
Upgrading components for artifact weapons starts off with fairly low requirements, but as you gain more stages and levels, can become quickly very expensive.
For example, upgrading one component on the Infantry Blade from Stage 0, Level 0 to Stage 1, Level 1 costs 11 components, 10 forge tokens and 1 breakthrough token.
However, upgrading 10 levels on the Infantry Blade from Stage 5 to Stage 6 costs 94 components, 166 forge tokens and several breakthrough tokens!
Forge Tokens will need to be saved before Artifact Events to a jump in level or stage worthwhile. It's better to focus on one attribute at a time, e.g. Fortune or Military rather than going for all four due to the sheer number of Forge Tokens needed to upgrade.
Attributes increases with stage and level as well, and they do not increase linearly. For example, the first 10 levels of the infantry blade gets you +5.1K attribute increase. However, 10 levels at stage five nets you +18.52K attribute.
Every 10 levels, you can upgrade your stage, which requires the same number of breakthrough tokens as your stage + 1.
Details are linked below for which components are needed to upgrade each weapon, how many forge tokens are needed per level, as well as how much each attribute increases with an upgrade.
The cost calculator above provides comprehensive coverage on items needed for upgrading artifact weapons.
