@mutsutakashi If you go back to the earlier chapters, you can see that he bandaged them up (off-screen). And at this point, it's been a couple weeks since he got his fingers chopped off, so he probably doesn't need to worry about bloodloss anymore.
@mutsutakashi But he still was pretty chill for a person who just lost 1,5 fingers back then. Had no trouble operating his injured hand. So, whatever.
And the knife is still the sharpest blade ever. Clothes, muscles, bones? Like butter!
