I think they do yes.
I didn't really want to buy another one
I've got 2 of the Refina midgets for the plazi that are redundant now as you can't get the blades obviously.
The delehedy handle doesn't look right to me feels a bit weird as well.
Mind you I got the delehedy free courtesy of
@Pagey who couldn't get on with it. Which is why I've been using it.
I've been meaning to see if I could modify the Refina trowel to fit the blades but not got round to it.
I keep persevering with the speedskim when I can I just can't seem to get the hang of it
I've tried covers bent up slightly, corners normal. Tried it on wet gear and firmer gear.
I like the idea of it which is why it's not in the skip yet
