My review is not original. If you regularly search the internet for "wood is a good review" you will find a number of professional, respected and revered authorities who agree. I have nothing to add to the heartfelt respect and support for this company and their hammers. I've seen this line of products touted as a solution to elbow problems, fantastic protection for expensive or fragile tool handles, and the best idea for the home carpenter who wants to be respectful and cut Mori as quietly as possible. This list has no end. All hammers come with a lifetime guarantee and their performance is worth every penny of the investment. I do not benefit in any way from the praise I have written here. This simple tool is so amazing that it took me some time to write it.
