Peter — Regarding your statement that you like shops with limited tools on offer, I'd recommend any of the HZ tools Riv sells. If you need a particular tool under the HZ label, pick it up. I doubt you'll be disappointed.
I have the cable cutters, chain link pliers and chain breaker. Recommend them all.
Yes, I prefer my Park chain link pliers because the handles are more comfortable, plastic grips are helpful in high leverage situations. Yes, I understand one of the driving design principles behind HZ is
no plastic!
Chain breaker is awesome for the price. Cable cutters are good!
As Russell mentions, Knipex makes some absolutely great stuff, recommended by electricians I work with. I have a set of their diagonal cutters and used them to cut cables before I had a proper cable cutter. They worked but proper cable cutters leave you with a cleaner cut, if that's important to you. Jobst Brandt said diagonal cutters did the job just fine ;0)
I don't need them but I wouldn't mind having a pair of Felco cable cutters made in Switzerland because I like the brand and their designs. They offer replacement parts to keep their tools in service. My friend is a professional gardener and uses Felco No. 7 shears. I enjoy tearing them down, cleaning, greasing and sharpening them for her a few times a year. I believe I've seen Mark Abele at Riv photographed using the Felco cable cutters in the past and maybe they're even shown in one of the Riv catalogs
