I can get it done with 2 to 3 inches...give or take a little on either end. I've even used those Micro Canadians from Bark River and did just fine. I've found over the years that I can get done what I need doin' with less than what I once thought necessary. Our ancestors did it with chipped prices of obsidian and chert. It ain't rocket science. Now, regarding doing it with a fine handmade custom fixed, drop point blade...that's an enjoyable experience altogether different...like drinkin' a real good bourbon
