If you carry a saw regularly then the Pro would compliment it well. Its better for battening. But as a general knife then all that thickness just gets in the way.
For all those thick blades I find they get in the way of seeing what you are doing as they have to be worked at a steeper angle. Sort of blocks your view working angle. Deep cutting of say an apple then they tend to split the fruit rather than slice like some thin paring knife. We all love the thinness of say a Mora for whittling, but they aren't very robust. Thick stock blades have to be used differently, but all that steel should give the blade real practical strength so can be put to bigger work loads. The Pro's scale doesn't make it a chopper, not having the size and weight required, so its still a cutting machine that because of its wedge battens better. That wedge compromises efficiency as a cutter. Whats most important?
So as said, very different tools.
All adds to your cutting armoury and is different enough to justify. The Pro is well executed of its type and one that will last a life time. Thing is, are you going to use it enough to justify what is a hefty price tag? You can only take one knife on an adventure, and selling a used loved knife is rarely worth the hit. For that kind of money there are some other Gukki things you could buy instead. But then again its nice to add something to the knife armoury that provides more to the mix and knowledge gained. Your call.
