Out of the six I got, 3 were hair popping sharp, 1 was close and the other two didn't want to shave but I wasn't going to dig in to my arm to make sure.
I really like the look of the knife.
The feel of the handle is good in a few places but the handle has a squarish profile which makes some grips feel uncomfortable. It's not a big problem but I think a couple hours with an exacto might make a much more versatile grip.
Four of my six have the missing ears issue. I could care less. It says Infi, that's enough.
Now I just have to take one of them, carve up the handle, beat the crap out of it and then remove the blade coating. It should be fun.
