😪😪😪skill level is definitely lacking here...
I realise that I may have been using less pressure than needed. After the recent post, I went back to try again, but with slightly firmer pressure and indeed the result was better than previous attempts.
Another that has me stumped is how does one manage a boning knife that has a slight S-shaped edge from tip to bolster? Tried Googling and YouTube, but I can't find anything on it.
