Tool of the trade - Point Turner

Now this is something that I cannot do without. I inherited it in one of my op shop sewing tin finds and now that I have it, the tool is invaluable. It makes the difference in the corners of collars and corners being turned completely out.

Curvy bit for curvy corners,

pointy bit for pointy corners.

Keep your eyes out for one.

Now that's a tool!

It took me a good while to work this one out. I got it in the fantastic stash from Betty (my friend's relative who had worked as a seamstress), so I knew that it must have had a really good use. I finally worked it out & it is REALLY, REALLY useful - still.

Can you work it out? Those blades are sharp & turn around so that you can select each one. It measures 12cm long & the circle is 5cm wide & the blades are 9mm, 14mm & 18mm wide. Does this help?
