I’m really rather surprised that no one has addressed the proper role of a knife steel.
Steeling realigns the edge and should be used after (“before” - if you store the knife in a drawer where it might bang around) every single use!. No excuses. If you steel your knife every time, you’ll only have to hone your knife every 6-12 months or more, and it’ll still be razor sharp every time.
There are several techniques of steeling. No matter what technique you use, the steel should be longer than the blade.
The one I think is easiest for a beginner is to place the tip of the steel on a counter , and with with the knife at a roughly 22° (your preference may vary) lightly slice the knife aling the top surface of the steel, as if you were trying to shave the most infinitesmally thin slice of the steel. You should pull the blade slightly as you steel, so that each stroke begins at the haft of the blade and ends with the steel at the tip.
After several strokes, do the same with the other side, maintaining the same force and angle. You’ll have to use a little body memory because the edge will now be the rear edge of the blade, and the stroke will in some sense be 'backwards (unless, like me, you’re ambidextrous, and can switch hands and steel from the other side)
They say you should do 10 trokes on each side, then 5 then 2-3 then 1. I’d do that during the first month or two while you’re learning, or when the knife doesn’t feel quite up to par. The rest of the time 3-4 strokes per side is plenty for routine use.
Be aware that is is a religious issue. The most I will say is that this technique is not “wrong”, though many people will insist it is utterly wrong, and may become violent if they catch you, say pulling an edge ‘backwards’ aling the steel or committing other heresies (I, myself, considered this heresy for at least 10-15 years) There are other techniques for knife steeling. Read about them. Personally, I think that you should do whatever seems most comfortable (while yielding results) for you, because otherwise you simply won’t do it regularly. Periodically, ask yourself if the knfife is truly staying sharp, and try another technique if it isn’t. Even if it is still working, you might find a more advanced technique suits you better now. Try new things and grow.
In a pinch, you can also realign the edge with several strokes on an unglazed ceramic edge, like the bottom of some dishes. If you steel regularly, then honing and sharpening may never be necessary (or so infrequently that I consider it a completely different issue)
Honing is, likewise, a religious issue, and I think Scylla’s description is as good as any. I’ve been sharpening my own knives, axes, lawn mower blades, etc. for over 20 years, and though I fancy myself fairly proficient, I definitely don’t do it the same way I did it 10 years ago - or even five - but I don’t think my current method would have suited me as well back then.
IMHO, ** true sharpening (regrinding)** is a serious business and should only be done by a professional - no more than once a year and probably not even that often (unless you absolutely wreck your knife through abuse or chip a blade edge) It’s a last resort and the few bucks you spend getting it done professionally every few years is well worth it, if only to re-establish your baseline, and remind you what the knife should feel like. Not all your knives will need resharpening at once - or even at all. having the whole set re-sharpened is a waste IMHO, and just asking for trouble in many ways (everyone has a bad day or an overeager apprentice)
Not every shop that hangs out its shingle is capable or interested in doing a good job. The guys at the knife shops at the mall (even the upscale cooking shops) often did a such sad job that I could barely delude myself that it was worth it. My current guy asked me to demonstrate my stroke (I actually bring something to slice sometimes) and discusses what he’s going to do. The results when I get them back are so superior to any pricey sharpening job I got at the fancy places that it almost inspires feelings of vengeance.
Serrated knives cant be resharpened. Ginsu? Why even bother, when you can get a new set for $1-2 plus shipping on eBay?
