A 22 year old knife enthusiast surely has a lot to learn. If he can pay attention to more experienced members, lose the attitude, and get serious about building a good reputation on Bladeforums,
his future knife hobby could be so much more rewarding.
There is of course no substitute for experience.
I hope he learns about a type of defect to look for and genuinely did not know. I would hate to think that he is purposefully trying to pass a knife on with a defect.
@Masonivy5 unfortunately judging by the video creativeguy posted it is apparent the Sablya has lockrock. Probably best to disclose that in your sale unless you want to deal woth the headache of having the next purchaser send it back.
