Here is my Field Sharpening Kit For Knives And Broad Heads that I carry in my arrow case so that its with me in my truck, at camp, available in the field, etc. Similar to the set up I use at home with some slight tweaks. Its important that you have a way to touch up or resharpen your knives and broadheads when you are away from home. This is the system I find works perfect for me.
