I like it. While there are limits to its utility, I think it's great. Actually, wakizashi style blades were originally designed to be carried everywhere at all times. So, although in todays society it's not really accepted to carry a large blade everywhere, they are not impossible to keep on you all the time. But, I guess Samuri did not have to get in and out of trucks.
Of my big knives, AK,KZ,Gladius and the NMFBM (sold), I prefer the NMFBM for actually use. The AK is a close second. Then the KZ and then the Gladius.
But between the three you mentioned...
Besides the handles and based simply on steel, I think there's a place for all three. The Scizzy in S7 has crazy tough steel for impacts, the SR-101 has the best edge holding ability and Infi a compromise of both with better stain resistence. I'm over simplifying here, but that's my simple logic. If you were to only have one, regardless of price, the AK makes the most sense. For chopping trees, Waki, for demolition...Scizzy. Because there is definite overlap in their capabilities, it is necessary to go to extremes to see the difference in performance.
