Looking for a Tuning Fork

I want to get my hands on a couple tuning forks for bolt removal/replacement. I don't have the tools on hand to make them unfortunately. If anyone has some premade, or could them for me, that would be much appreciated. I want two of them.

You might contact Greg Barnes of ASCA. There were some Lost Arrow piton tuning forks available through ASCA several years ago. Perhaps they are still available.  http://www.safeclimbing.org/contact.htm

I prefer a big tuning fork made from a 1" cold chisel or from a tile chisel. Cut a 5/16" slot and grind the tip to a more acute angle. Drill a hole in the handle for a lanyard, or easier, cut a groove around the circumference for 1/8" cord. These are capable of removing a 5/16" buttonhead. 

To protect the rock from gouges, consider using a piece of sheet metal. A 4" round disk with a single groove from outside edge to center works nicely. Slide the disk under the hanger and insert the tuning fork between hanger and disk.

It takes but a few minutes to cut a slot with an angle grinder and thin cut off wheel.  https://abrasivessafety.com/en-us/cutting-off/angle-grinder/reinforced-wheel

Guideline #1: Don't be a jerk.
