I'm really glad that I have chosen, despite some negative reviews of this knife.
In my opinion, these negative reviews come thereby able that the instructions were not read correctly and implemented.
Therefore, please note the following advice (which is also in the manual):
For the final cut when the guide rail already seated on the cutting board:
Simply pull up the knife and perform the final cut with the knife tip. That's really quite simple.
But be careful: the knife is really very sharp!
If you can find my review well, then please click on my post "Was this review helpful to you?" to "Yes". So I can get some feedback and an incentive for further reviews. Thanks a lot for this!
