Stuller still stock's and carries them and I seem to recall seeing them in other jewelry tool catalogs as well. Nothing works as easily as my Starret divider. The spring tensioner is perfection in tool making. Turns with ease yet still holds the position tightly.
Anyone know how they are measured? I have yet to figure it out, as it doesn't seem to be by the length of the "legs" or the total length. Starrett RULES in machinist tools, but the Brown and Sharp 800's are also VERY nice dividers.
