Knife porn thread

I inherited a crapload of my dad's Sabatiers when mum and dad retired and went back to Spain, dad was a chef... They really need to be sharpened, there's only one with a decent edge, I can't use the others... 6-7 knives, a coupla really old steel ones (i.e. non stainless Sabatiers from the 60s)...

Tips for sharpening*, just buy a whetstone?

• I have a steel, which I can never get a decent edge from but as the knives are all blunt as fuck I guess that's a big ask... I've been using a knife sharpener like this one for years...
