This appears to be a duplicate of MC-140397.
Its similar, but it also works on other items, MC-140397 seemed to be just for swords? Also you can stack more than 2

the grindstone removes enchantments from tools, and - if damaged - combines their health. Here both swords have full health, so you get both back. I think this is correct.
You can combine the enchantments using anvil.
I was not trying to combine the enchantments. I was just testing out the grindstone functionality. I tried out with swords that weren't of full durability and also got the same result.
Either way, the output should not be a stack of ́2 diamond swords I guess.
This issue is not consistent though, sometimes Minecraft produces the 2 swords and other times it doesn't.
I'm able to reproduce this in 1.14.4 by using two identical swords with the `Unbreakable` tag.
Based off @Andrio Celos comment, from testing it appears that currently it is required that the swords be both unbreakable and have an enchantment. Not possible otherwise. A sword that will work in 20w30a can be given by the command /give @s diamond_sword{Unbreakable:1,Enchantments:[
{lvl:1,id:"sharpness"}]}
I am unable to reproduce this issue in 20w51a.
I am able to reproduce in 20w51a and 1.16.4 using the command provided by Bluecrab2 in the comment above.
Testing on reproduce there.
Steps to reproduce:
2. Get grindstone in inventory and place on the ground.
3. Middle mouse click on unbreakable enchanted diamond sword and put on any slot you placed.
4. Right click on grindstone and put 2 unbreakable enchanted diamond sword on 2 output and there is 2 diamond sword with unbreakable tag and its 2 stack slot.
It seems to only apply to unbreakable items, regardless of enchantment(s). I've updated the description.
Hi!
If it is possible, can the summary of the bug also be updated to cue in that this isn't always the case (i.e. by mentioning it only happens with Unbreakable items, "two outputs can be given" or language such as "When combining certain enchanted items")?
Video attached.
Affects 1.18
Affects 1.18.1
Can confirm in 1.18.2 and 22w13a.
Can confirm in 1.19.
Can confirm in 1.19.2.
Can confirm in 1.19.4-pre1 and 1.19.3
