Center Finders, any feedback on either?

Blacksmithing Tools

Checking out center finders, I came across two styles really.

Here is the first style:

Center Finder

And the second style I can’t find anywhere, but basically looks like a Z with pins in the corner, and the scratch in the middle of the middle line.

Any suggestions? Anyone make their own in the style of the video or have their own way of center scratching?

Cool Idea! never thought of that before. I like that first style. It looks like a easy build too. I think I’ll give it a try and then maybe move to the z style If I need to upgrade.
