While working on the 1mm and 2mm tool tip sets I also made 10 finger/spoon tips as well as 10 sculpting knife tool tips, each made of 1.5mm steel. So this is a size between the 1.0mm and the 2.0mm tool tips. These tool tips I will fit in wood/brass handles and sell them as 10 single tools with finger/spoon- and sculpting knife tool tip. I made this combination because for me this is the tool tip combination I used most of the time while sculpting. You can see a picture of this combination on the following picture.
And on the next picture you can see a comparsion of the fingert/spoon tip and the sculpting knife tip, each shown in 1.0, 1.5 and 2.0mm.
