Here’s my two reasons why I gave it a 4 out of 5:
1. The thumb knob on the blade seems to take a little bit too much pressure to open the knife. I think it’s because you have to place your thumb at a weird angle and could be fixed if the knob isn’t as close to the handle of the knife when the blade is closed.
2. Maybe I have fat fingers or a big hand, but it’s slightly uncomfortable when tightly gripping the handle of the knife. A few more centimeters added on or a bit less of a curve where the pinkie goes would be perfect.
Again, those two things are minor. I would still highly recommend this knife.
