Buzz!! do not be afraid to state what you think, you may be wrong, but when somebody hints or comes out and says you are wrong, you will learn something, get mad or upset and show it on the net and they will quiet responding to you, i think your # 2 photo is a knife or blade, i think they mean the same, and use them that way. your using uniface correctly is what let me respond to #2 photo. if when you start posting on your on if you would show both sides of the artifact, and include an american coin or ruller, i do not know what most people like but i like the coin, your choice eather way please incloud one of them for size refference.. these two things will help anyone to name your artifacts..
