Here is a totally different idea. There is a little tool called the Workshop Tool Sharpener, that has inter changeable sand belts for sharpening knives and tools. It does not do so good for broad heads, but really is nice and quick for knives to a razor sharp edge. It will sharpen knives, scissors, and can be used as a portable hand held belt sander for axes, etc. I got mine from Amazon for around $65 with free shipping. You can search Utube and see some demos. Would make a gift of something they are unlikely to ever get from someone else.
Congratulations on the marriage. Marriage to the right woman, when submitted to God and done His way, is an awesome deal. Been married 32 years now and it has just gotten better and better. She is really my best friend.
