Just discovering the wonderful world of Circlips! Looking for advice on pliers.

I have just taken a look at our lawnmower and purchased a replacement “circlip” (cool name), I’ve now gone down a rabbit hole of circlips and pliers! But it’s super confusing. I’m looking for a tool that would do this Circlip.

I have come across circlips on the past at home, so would be willing to buy a set if that’s what people would recommend, but I at least need to be able to work with a Circlip of this style and size. I’ve gotten as far as working out that it’s an external clip, but most of the tools I can find seem to have two prongs for holes, which this clip doesn’t have!

Looking for UK available brand suggestions. Thanks in advance!
