I got the fiskars this year for house plant trimming. It has a kind of blunt point though when sometimes we want a real sharp/needle point for fussy cutting...so I like the one posted above better. But the action is good. For price comparison, I see that one for about USD$11. But that might be another way to source them-plant trimmer as the UK is flower central to me

Or stationary stores. Or quilting stores...
Peeking around over there...
Buddly crafts has the Holtz ones but they are pricey
Oddly I don't see any at Hobby Craft and neither does Crafters companion. huh.
Ok here we go-they are on Amazon UK.

If you ask for spring loaded scissors you see a bunch. They are only showing me ones that will ship to the US so you may see more than I am.
They also look like they are on Ebay UK.
HTH
