Thread: Knife sharpening

  1. #1

    Knife sharpening

    I like to keep my kitchen knifes in decent order and periodically use a sharpening stone and hone frequently on a diamond coated steel although the stone sharpening is a bit of a PITA if I am honest.

    Now I know that a lot of people sharpen their knives using a bench grinder with an appropriate wheel. I would think that this is easier.

    Anyone do this? What grade of wheel is best used? Any advice welcome.

    I use a Spyderco Sharpmaker - works a treat (and is pretty simple to use once you get the knack).

    Details here:

    I was trained as a butcher many years ago and I still do the old butcher trick with my knives. That is to say sharpen them every time I'm going to use them on a steel. It works for me. If they do need re-profiling I use a bench grinder but it's ony needed very occasionally. To be honest once they start to thin out then I buy new ones as the constant sharpening does tend to wear them away.

    That is good advice. I use my steel pretty much each time I use them (I can't say the same for the gf though although she hardly uses them to be fair about it).

    I've only sharpened one or two with a stone as they infrequently need it. Saying that though one or two could do with a sharpen and I'd like to sort it and thought using a bench grinder would be easy.

    What wheel type do you use?

    I have tried to follow this guide, but usually give in and take my knives to be sharpened. I find a simple stropping against newspaper works wonders. In reality, getting the 7-8 degree angle is just a matter of practice, but unless you're doing this regularly, I imagine it's a little tricky to get right each time. Practice probably makes perfect, as with most things.

    +1 to that. We use that on our Global knives. Imagine it will work the same on others:

    For a functional edge used to cut non specific things and which particularly excells on veggies & meat:



    Cost 3 Euro.

    For chisels, use on fine leatherwork or fancy knives it is too course.

    Cheers,
    I bought and use a Sharpmaker as well, I like the way it controls the angle of blade to gie a constant edge. I also bought the diamond course 'stones' to reshape any knives and the extra fine stone. I am able to get my swiss army knife frightenly sharp using the extra fine, although for for kitcten knives I go to the standard ine stone.

    As already stated I currently use a stone.

    My knifes are kept sharp by regular honing and so need infrequent sharpening. I'm not interested in any knife sharpening "gadgets", although thanks for the recommendations, I'd rather either use the stone that I already have or use my bench grinder. I just wanted to know what the best grinder wheel would be to use.

    recently took 5 knives for sharpening as they had gone blunt and could not get them sharp with a steel. since they have been done, have had no need to use the steel on any of the knives and need to be extra careful as a few times have almost sliced a fingernail off while chopping vegetables.

    it maybe that i have a good quality wooden chopping board that looks after the knife edges.... glass is the worst thing to use for a chopping board as they will blunt the knife edges in next to no time.

    also it costs me more in sponges now as the knives literally cut the sponge to shreds when washing them.

    Apologies - the essence of your request was lost on me after a long day and the vagaries of conversational drift on an internet forum.

    I wouldn't describe the Minosharp as a 'gadget' though, any more than I would describe Globals as fashion knives. I switched to Global following many recommendations from surgeons I have worked with who generally know one end of a sharp object from another. Whether they have bench grinders in their garages though is a different matter.

    Hopefully someone will be along to tackle your request :)

    Another vote for the Minosharp. Bought one just before Xmas and it's sharpened up our knives a treat.

    Minosharp are great but it depends on your knife.

    Because Minosharp is designed for Global type knives which are thin where the blade joins the handle (sorry don't know the proper term) it sharpens the whole length of the blade.

    But with my European style knives namely Wursthof and Henckles, they are a thick V near the handle which fouls on the Minosharp guide and doesn't sharpen about 2cms of the blade nearest the handle.

    I sold mine and bought a whetstone.

    I use a wet stone wheel with a pretty fine grit, if I need it. Not sure of the make I bought it years ago from Screwfix. As I sais I don't use this very often. The steel does the job if you use it every time you use the knife.

    Fullt agree about the surface you cut on. I prefer wood but plastic is OK. I never use glass.

    You take kithcen knife advice from surgeons hence bought 'Global' knives?

    I used to just take my knives to my local butcher every time I bought some steak - I should learn to do it myself though.

    Why not?

    Surgical colleagues usually have an opinion on most matters, but I'd trust their advice regarding sharp items every time. Lots are into fine dining anyway. If I needed a source of fresh langoustines or partridge then I'd probably ask a surgeon. If you need performance car advice then there is no one better to ask than an orthopaedic surgeon.

    As Global for some odd reason seems to trigger a certain knee jerk reaction akin to discussing Rolex watches with ditto owners, I'll stick to that understatement of the century.

    Knife sharpening

    I've never met a surgeon who does not have an opinion on much. The nature of what they do means they have to believe in their opinion and this often means they seem to speak on non expert areas with some conviction.

    I do doubt that aside from being a cutting instrument that a kitchen knife has much in common with a pearing knife.

    Fair play lads, but this is a watch forum let's not forget, so the chances of professional chefs turning up and offering their opinions on which knife/sharpener/bench grinder/wet stone/steel are probably pretty minimal. When they do then we can all sit up and listen. Until then we can just pitch in with our own experiences, which are most likely going to be from a domestic usage point of view.

    Globals do the trick for me and I don't feel the need to go any further upmarket. The deal with Globals was sealed for me when my partner inadvertently removed the tip of one of her fingers when preparing some veg for a pizza. If they are sharp enough to cause a trip to A&E then they are sharp enough for me.

    part of the reason why i had mine professionally sharpened was because they do knife sharpening for professional chefs. it was a small shop in plymouth that is an old style cobbler shoe repair key cutting etc the results were fantastic and i haven't needed to use a steel on the knives yet.

    i think it was £1 per knife my biggest worry was knowing i had 5 knives in a briefcase walking through town worrying how i explain if i get stopped by a policeman!

    I use one of these on my Global's

    http://www.axminster.co.uk/images/pr.../400126_xl.jpg

    followed by an old fine old stone

    Spend an hour in the garage at a time listening to the radio whist sharpening all my knifes (I wonder what the neighbours think :-o)

    I have found that some of the automatic sharpening gadgets are a tad course and aggressive on the blades.

    I should also add that the wife always complains about the knifes as she tends to have the odd accident when first using them!

    Thanks for that btw Jesper, I really second this observation.

    I have a "set" of Globals, and a plethora of other Kitchen knives of varying provenance and quality.
    The pick of them is probably the 18cm Deba. I only wish the handle went further forward, but it is a great knife nonetheless.
    regardless, they all get sharpened with the Global whetstone system, a two-part stone at 240 and 1000 grit, this one.



    It takes me about an hour.

    I also have two "utility" 6" knives that get the butcher treatment, used pretty often and sharpened with a steel every time I use them. Sure, they are sharp, but it is not a sustained edge, and dulls quickly, because a steel doesn't really sharpen, it raises a sharp burr, which is fragile and easily taken off.

    Global knives are, imho, not all that, but neither are they crummy overpriced tat. Their flexible blades are best avoided, as I see no differential quality in that steel that justifies the price, but the hard (and very brittle) Molybdenum / Vanadium steel can hold a true edge for a long time though. I do my hour's knife therapy once every 4 months or so.

    And I don't touch them in between. Especially not with a steel.

    My one observation is that polishing the edge (using the high grit side, or stropping with something similarly fine) is vital in creating an edge that stays the course.

    The rough stone makes the edge, the fine one ensures you keep it.

    D

    Perhaps I should add two things.

    First, the longest lasting edge in my all of my knives is a slim chinese cleaver I bought in the chinese supermarket in Bristol for £6.

    Secondly, I have been in quite a few kitchens and professional cutting environments. Hardly any use expensive knives. They mostly use cheap ones that are sharpended often. Like soldiers and G-shocks. Cheap and capable

    as you are not far from plymouth, try the cobblers in the same street as the newmarket pub. it costs £1 to have it professionally sharpened and your post count is goine ever so fast! read the announcement at the top of the page and donate some money to good causes.... eddie might be a little more forgiving if you are generous, and not just using the forum for your own personal gain/discount!

    Ah thanks, found it now. Indeed, my usage profile means that I don't usually see the main forum subforum menus.
