I have one of those. It’s only shortcoming is the length (it’s literally a shortcoming…). The hook is well designed and proportioned. I prefer the Italian hive tool myself, but it’s not as handy to carry around, but it is handier to use on the hives:

For a pocket tool, I don’t go anywhere without my custom Leatherman:
With parts from five different Leatherman tools, one swiss army knife and two custom blades. If you use just the blade and twist to pry (do not pull up or down or you will break the blade) it works most of the time and the pliers nose works for prying between the ends of top bars to pull out a frame:
A regular “Wave” or a “Surge” would work as well for a pocket hive tool, but would lack some of the other features. I’ve often used a regular pocket knife the same way (twist, don’t pry) and then close it and use the handle to pull up a frame.
But of all the pocket hive tools on the market I think you got the best . I have some that are smaller and lighter, but not as functional.
