A little off the subject, but a note on sharpening.
I bought a cheap belt sander 30” belt 1” wide. I can now shave with all my good knives. A Canadian company sells all manner of Belts, 250 grit to 1200 grit to leather strop belts.
I have maybe $100 invested totally and after a little practice free-handing the edge angles is simple.
What is the company?
