Honestly, I don't think the pocket knife thing is much of a plot hole. Yes, it isn't normal, but it's not something that will ever pop out to a reader. Bringing more attention to little details like this is not great.

There is a fine balance between giving too much information and having a plothole. Most of the time you want to aim for the middle, if the plot hole is not something serious (as in the case of a pocket knife).
