Any Krieg officer who goes into action without his shovel is improperly dressed.

Well this is a krieg 3d print I composited to have a "power shovel".
Power Shovels do not exist anywhere in canon lore, but there's no lore reason a shovel cannot be made into a power weapon.

A normal shovel is a meme regarding Krieg. It does not have much basis in lore.
Krieg were famous for trench warfare. Trenches are dug with shovels. Memes about them fighting with shovels ensued.

I decided to take the gag a step further, by printing and painting power shovels for all the power weapons in my army.

In my homebrew lore, they're from a planet that specialized in ship breaking, and they first used power shovels to dig furrows in adamantium prows so they could be broken and re-processed.

no nothing special about it.
the Krieg and their shovels are just a huge meme in the comunity.

there is afaik nothing in the lore about their shovels.

the krieg are based on ww1 trench warfare.
and aparently it was a common practice (or at least often depicted)
to use sharpend entrenching tools as an improvised meelee weapon
