Well as much as I don't like to say it, but I agree with Grump. I believe them to be fair and accurate.
But I still agree that he is a curmudgeon....to coin someone's phrase..
The blank looks nice and it's on the old popular one diameter pen as well. Some like them, some don't.
However, What brian is saying is it could and should look better and believes that you have the ability to make this type of blank top notch..
Brian has attained that on knowing what abilities you need to even make a blank like that and the skill involved so knows improvements can be made.
Well done for posting on here and look forward to many more of you posts on segmented pens..
