Hello again all

Is there such a thing as a "scribing divider" ?

Useful for when working on "black" steel?
Will cut-through / mark the mill-scale surface?

Maybe about 10inch/250m to 12inch/300mm "legs".

If I recall rightly I have seen dividers where each leg has a smallish
about 3mm very hard steel/carbide cylinder ground to a point. Which
can be demounted/unclamped and resharpened.

If so, what are these known as?
Not doing well looking in tool catalogues.

Else - is the answer something else like dividers with a point at one
end yes, but a chalk / soapstone at the swept end?

Regards,
Rich S

I have a divider that has a sleeve with setscrew to hold a pencil or
round soapstone . It's about 9-10 inches long .

Trammel points yes.
Forgotten about those. Yes they would be "the thing".

I freehand grind my scriber tips from broken HSS taps and 1/8" shank carbide drill bits. A pin vise collet can hold them.
