I believe that in forums NO ONE should ever be put on the defensive! It's the same as telling someone thier questions are meaningless and that they should just shut up or leave... Regarding my thread about use of a light tent, AlexB gave a great reply. The fact is, I didn't get all the answers I needed and without getting in to a long explaination, I am not satisfied with the images I posted of the knife. All I wanted was for more people to respond with different views, and images if they had them to offer. Now, I am hesitant to ask any question on this forum in fear that I might be repetitious. I expect no resonses to this posting. I simply had to express my feelings.
