Lately I have been seeing the HI AK Bowie knife come in at about 21-23 ounces. In the past I had seen the AK bowie being over 30 ounces in weight with a spine thickness of 7/8ths or 1/2 inch almost. Has anyone purchased the lighter AK Bowies? Why do you think they switched recently to making AK bowie so much lighter in weight? The 30 plus ounce AK bowie does seem insane but I am just wondering what the pros and cons are of each blade?
