I like that very much there is perhaps in some instances another stage ( I have copied and pasted the 4 stages to notes) .
A master Katana sharpener said that whilst he trained 10 plus years he got to the stage where he was happy with his ability in the end ; but once he became a master he has never been happy with the end result I must say that I fall into this category of displeasure the better I get the more disappointed I am in the results since although the faults are a lot less the questions remain even if others are impressed I always question my work and I also remember what I heard once which is people both judge you by your worst work not your best so the aim is to improve the lower end of the work.
I had a high school English teacher, a Mrs. Salisbury, who paraphrased it as:
A Freshman doesn’t know he doesn’t know.
A sophomore knows he doesn’t know.
A Junior doesn’t know he knows.
A Senior knows he knows.
I’ll take Gib’s version, as it has a lot more class. And for sure now I’m a Senior, but according to the pattern, when it comes to knife sharpening, I’m still in my Sophomore year.
