I’ve been using Oetiker clamps for a while. Stainless steel ear clamps. One time use.
OEM on Volvos and very convenient for most places where you would use a hose clamp. They go on quickly, hold tight, don’t loosen and are cheap.
CV boot clamps are basically big Oetiker clamps.
So, Oetiker clamp pliers. Name brand are moderately expensive. Lots of knock offs out there, but I prefer good tools. I recommend the kind that have both the front and side clamp in the pliers. Particularly around CV boots, you might need the versatility.
