I took a wood file and went to work on the grip of a custom bow so it would fit my hand better. The grip was way too high, and I like a more relaxed grip. By the time I got done with it, the bow fit my hand like a glove perfectly. I shot 5 times better with it and killed a turkey with it last fall. Did I hurt the value? Yes, probably, but do I care? No because now it's mine and if I couldn't shoot it the way it was then it wasn't any good to me. Now it's a killer in my hands and it's got mojo in it.
