@ThatGamerBlue What version do you use? I use latest version on 1.10.2

With working as intended he means that the item is non-enchantable.

You can enchant vanilla axe with Sharpness, but you can't enchant Mekanism axe with Sharpness. For me this is unexpected behaviour

Are we sure they are supposed to be non-enchantable? The config file has an "enchantability" setting that I think defaults to not 0.

In Hermitpack, Obsidian is set to have an enchantability of 40 (which I assume is the default). For comparison, gold tools have an enchantability of 22.

As roboderpy said , you can enchant vanilla axes with sharpness enchant. I thought we could also do this in prior versions of mekanism.. Has it been removed ?

Working as intended. @aidancbrady /close

I stand corrected, Mekanism items are enchantable.

I know that, I initially thought they where not enchantable at all. Currently the axes look like an ItemTool for Minecraft and thus only allows ItemTool enchantments. Somewhere in Minecraft/forge must be a check: if axe, allow sharpness. I'll take a look where it is and try to fix the axe :)

Took a look at how enchantments are dealt with in Forge/Minecraft. Looks like (in 1.10) it's hardcoded to instances of ItemAxe. I only can think of a dirty way to fix it, not a nice and clean one.

This looks better right?
Was easier than expected.

Can be closed when the 1.10 branch is merged to 1.11.
