Explosive curse unbalanced

[MarioSMB]

The problem

The "Explosive" curse seems terribly unbalanced currently;

• Vanilla mechanics allow hiding behind a block and digging to freely explode nearby terrain making it "free" infinite TNT
• It is far more dangerous and obnoxious than any other curse, rendering the tool virtually useless for regular gameplay
• The damage from the explosion is more effective against mobs than it is the wielder, except for the fact that it will destroy your base in the process!

I believe curses should be a downside that you may want to put up with to use a powerful tool, this curse does not fit that paradigm as it does not allow the tool to be used normally.

My solution

What if the explosion didn't do any damage to players or blocks, but only to items?
Mining with an Explosive tool would be bearable as you would have a chance of losing what you mine rather than blowing up the area, while mobs killed with an Explosive weapon would have a chance to yield nothing.

I think this would be far more intuitive and less intrusive on gameplay while still reaffirming that it is a curse.
Thank you.

the only thing i read is skill issue, you just want an op explosive pickaxe or whatever, its good as it is, if you get the curse you get rid of it and start again

The design of this specific curse is enough to warrant removing the mod.
It is not a skill issue, and sure one can just remove enchantments from their tools, but that defeats the point of "living with the curse" so to speak - or is it preferable that you just keep rerolling the tool until you finally get something that isn't obnoxious? Because intending such a design makes this more of an annoyance than something worth playing with.
