Knife Maker's Centre Scribe
thingiverse
This is a center finder for a scribe which I bought from Gameco Artisan Supplies. I use it to find the rough center on my knives since i don't have any metal machining capabilities. If you don't have this scribe there are some files for editing. It has a 15 degree angle and holds the scribe with friction.
