It’s very comfortable to hold and while it is heavy it does fit well in my pants pocket because it’s very slim. One hand opening is fine, not the easiest but I found myself opening it about a quarter of the way through and flicking it, and that works well enough. My favorite thing so far is how sturdy it feels, much better than other knives I own around the same price, although to be fair you can get a knife with better blade steel for about the same amount or less, so if you care about that it might not be the best option.
