First and foremost, yeah, it doesn't look real (which isn't a big deal)
Second, just add
blood capsules to your routine to prank your friends or audience. Everyone knows its fake but if you
stuff a blood capsules in it, you can pop one as you push in the blade and make it look like you
messed up.
It gets big laughs (but I assume eventually someone will get mad over me doing
this)
Just FYI about the blood capsules, you'll have to buy your own fake blood and
capsules from somewhere like Amazon and then delude it with water before loading your capsules so
it's runny. Kind of a process but trust me, it's well worth it
No one is gonna believe
you're actually separating your finger but people will easily believe you messed up and buy into you
cutting yourself
