I have only used the Blazing Cleaver and the Blazing Pickaxe so far, the Pickaxe works as intended however the Cleaver appears to continue taking damage, and it might also void item drops from mobs, which leads me to believe it might have properties from the Shadow Blade sword instead.
(Killed 10+ Blazes with the sword and received none of the drops, including 2 pigmen who should at minimum drop 1 nugget or 1 rotten flesh)

This issue has been addressed in 0.2.3. Thanks for the report and feel free to re-open if need be.
