Hello, has anyone else noticed that there are 2 slightly different ARS Flipshank folders with the same title, but slightly different blade shapes near the tang? If you look on Knifecenter, the black and foliage green ones have a different blade shape there than the orange and toxic green ones. Does anyone know why this is or what differences there are, or which one is better? They are all the same price. Also, are there 2 versions of the Al Mar Shrike folder? It seems like Al Mar Knives might have made a slightly different design to replace an older version, but I'm not sure. Any info is appreciated.
