(Or at least to the best of my knowledge )
Over the years I’ve seen many techniques for sharpening knives, from small minuscule grinds on every section of the blade to what can only be described as abusing knives.
If you didn’t already know the most common tool for sharpening a knife is called a steel, which funnily enough is a piece of strep used to grind the blade of a knife back to sharpness.
There’s literally thousand of types of steel (the metal) and a hell of a lot of types of steel for sharpening knives and I’m not here to list them, but this https://www.bladehq.com/cat–Steel-Types–332 is quite informative if you’d like to know.
Other than steels I’ve seen a few other things used before including other knife blades (best to use old unused ones if you have to resort to it) and sandpaper which my current head chef uses to great effect on serrated knives, starting with the coarse grit and getting finer.
Anyway, a sharp knife is pretty important to cook efficiently so onto the sharpening!
I don’t know if any of the terms I’m going to use are right, or if this is even the best way to sharpen a knife but it’s always worked well for me.
- Take a steel run it under a cold tap just to get it wet or run the knife under water instead.
- Put a fist in front of you like you’re doing a thumbs up, you want to hold the steel with your thumb on the top and the rest of your fingers supporting the grip with the steel facing downwards.
- Take the knife and try to get it at about a 20° angle to the steel.
- Now you want to do an up and down grinding motion, kind of circular for about 8 rotations, the knife blade shouldn’t leave the steel.
- Repeat the grinding on the other side of the blade, with the other side of the steel (right or left depending where you started)
- Then return to the original side of the blade you were working and place the heel of the knife (bit of the blade closest to your hand as you hold it) and run the blade down the steel like you’re slicing, as the blade travels down pull the knife back towards you so as the blade reaches the bottom of the steel the tip should be the last bit touching before contact is broken with the steel.
- Do the same thing again on the other side of the blade, the repeat one side after the other for about 7-8 downward slices against the steel.
- Wipe the steel and knife clean and get choppy choppy.
Safety first!
I know it goes without saying really, but I’ve worked in kitchens for 15 years now and I still make mistakes now and then, I personally find cuts a lot worse than burns as it makes it a lot harder to keep cooking when you’re bleeding everywhere!
If you’re using knives around other people then don’t let them distract you, either put the knife down to talk to them or don’t take focus off what you’re doing because that’s all it takes.
Another thing I’ve seen quite often is people cutting themselves up because they’re trying to be fancy with the steel and go 200 mph.
Not only can you wreck your fingers and forearms (trust me I’ve done it before 😂) but it’s not the best way to sharpen a knife either (fast), it’s more important to try and keep the blade at a constant angle rather than go as fast as you can just to be cool.
I will get round to uploading some pictures to assist with the technique, my steels are always at work.
