I don't have a san mai kukri, mine is one I picked up in the philippines. I have never owned one of the gerber axes and won't buy one. A freind of mine bought one and got rid of it after one trip. We both tried it and it felt so unbalanced compared to a regular axe I almost cut my foot off with it. If your bound and determined to get one of these two get the kukri.
