Yes, you are right. Regular liners are reasonably priced and in good supply to many of us.
And it makes no economic sense to make our own regular liners for most of us in the good old USofA.
But I have some imported liners with unique line spacing that are no longer available.
And I remake them...
Thank you Sam, you are too kind.
I come from a time when tools were hard to buy and sometimes it paid, or you had to make them yourself.
Today there are so many reliable tools suppliers that I don't recommend a commercial engraver taking the time to make their own tools when the suppliers have...
When an old liner has been sharpened many times it becomes too short for use and more sharpening. If you can't just buy another liner you need to make one from the stub.
While you still have some good lines left on the stub it is time to use it to create a clone.
Clamp a straight, hard graver...
I have made many liners out of 01 (oil hardening) steel.
Used an old liner to cut them while the blank was in the soft state.
Then hardened and tempered them.
Hello and welcome Scott.
As one that does not do a lot of bright cutting here is my take on it.

Not on the graver material.
That said, the Cmax being harder will probably continue bright cutting longer than HSS...
Yes Arnaud, a lot of the old FN methods were to save time.
But we must also remember that they needed many engravers to faithfully reproduce exact copies of the many engraved guns that were shown in their catalogs around the world.
The customer bought and expected what they saw in the catalogs...
Little better photo, thank you.
From what I can see it looks well done and very appropriate for this old style revolver.
Best of luck with your new camera and let's see more pictures.
O1 tool steel needs to be heated to bright red hot for forging
If it is forged cold or at a low temperature it will form stress cracks or shatter dangerously

Hello Mitch , and thank you for all your good input and info.
For homemade punches and gravers I start out with fully annealed O1 drill rod or square stock.
When I make my 1/16" round gravers in the 3/32" brass tube I use fully hardened Cobalt, M-42 or micro grain carbide depending upon their...
