Dmitriy, wow you have an approach !!!
and what should we do? not having this approach to sharpening knives?
There are also many options here, but, unfortunately, I cannot answer you briefly.
Firstly, there is always an option to do nothing at all if
you are satisfied with the current state of affairs... Moreover, I personally think that this is often the best scenario for behavior.
For me personally, knives are
instrument and from experience I know that for the tool, so that it pleases and does not let you down, you need to follow: do with its help only what it is intended for, do certain prevention / replacement, monitor the general condition. Basically, there is no difference: it is knives, chisels, files, circular saw or food processor.
Coming back to the knives: I once bought a Japanese knife to see what was there, worked it myself, let my wife work. And we have this sharp / new (although it happens, even quite serious knives have a rather miserable native sharpening, since usually buyers of such knives still sharpen them for themselves and their tasks, and the manufacturers know this) the knife definitely liked for some applications ...
And then a dilemma arises: what to do with all this? For example, if I took a good knife and continued using it the way I used my other knives, it would quickly turn into exactly the same ones. In fact, in this case one could say "down the drain". As a result, there were rules: do not cut with good knives on glass (plates) or other hard surfaces (like bamboo), do not throw them in the sink, do not put them in the dishwasher, do not prick ice / bones, wash them immediately after using them, wipe them and put in place, etc. -
a bunch of restrictions... But as a result, we have really sharp / comfortable knives. And in order for them to continue to be sharp, they still need to be sharpened from time to time. My wife and I discussed this situation, and decided that nevertheless,
it's worth it... But, at the same time, we still have knives that "do not mind": we wash them in the dishwasher, cut them on plates and throw them into the sink.
Whether you need it, I don't know.
I only know for sure that, as an example, if you buy a really expensive Japanese knife, even if it has a good factory sharpening and you throw it into the sink with dirty dishes, you
can you get a large chip, which may not be able to "remove" (despite the fact that this did not happen with other knives). And occasional sharpening is one of the things that are needed to keep a knife sharp. At the same time, there are a bunch of knives that you don't want to keep an eye on, they won't be both sharp and comfortable. Or they can be sharpened, but the sharpening will not last long.
That is, it is important here what you want to get in the end: if you have a knife with a consumable that you do not mind, then the use cases are the same. If the knife itself is of some value, just as its condition is important to you, then your actions will be different. And everyone himself determines the range of things that are personally important to him, and to which he is indifferent.
not sharpen at all?
This is a good option in certain situations. For example, if you have ceramic knives that, due to their high hardness, are simply physically impossible to make sharp, then you can use such a knife until its entire cutting edge is crumbled, so that it is not very easy to sharpen them. Serrated knives, which, due to the fact that they have a hard surface on which you cut, only a small part of the cutting edge touches, blunt quite slowly: you can say they are more vandal-resistant than ordinary knives.
As a result, I use ceramic / serrated knives for some applications, such as cutting meat on a plate. I will never sharpen them, and when they become completely unsightly, I will simply replace them with new ones. For bones, special scissors are used, etc.
At the same time, at some point, I audited my knives: I corrected the cutting edge and geometry where necessary, sharpened them. But some knives, after a short time, again became dull, almost as they were: sharpen them, follow or not, but their steel was such that they could not be sharp for any long time. As a result, I also don't see much point in fiddling with such knives.
contact specialists?
Here, as in other areas, it is important which specialists to turn to: by and large, we spend a lot of time to find really cool specialists, be they a plumber or a doctor. And with knives everything is the same: there are people who love this business and do everything in the best possible way, and there are those who just want to get money with a minimum of effort on their part. As a result, I cannot recommend everyone to go "to specialists", since I do not know what the result may be.
Can you tell me how long after sharpening the knives retain the sharpness you need, that is, since you do not use musat, after what time do you need to sharpen again?
After sharpening all the knives, the first complaints that "this leg was sharper earlier" began to appear in about 5 months. Accordingly, it was worth sharpening them a little earlier.
But I do not think that this information can be really useful to someone, since everyone's conditions are different.
For example, we cook relatively little (and, accordingly, use knives) so that the knives "live" longer, I made a certain duplication: I have two identical petty 15cm, one santoku 18cm, and the chefs 19cm, 21cm and 27cm. Accordingly, as a rule, chefs / santoku are interchangeable with each other, just like petty with each other. This makes the "load" on each knife noticeably less.
Further, I would like to comment on musat: it is originally intended for bending / deburring: for knives with medium hardness (for example, all European knives), in the case of very strong influences, the cutting edge
bends and the knife feels duller. Musat was not meant for
sharpening... With all of this, most of the musats that are sold have a completely aggressive surface and very actively grind the knife material: that is, if you walk over the knife with such a musat, you can actually hold it
sharpening, not just deburring. Personally, I am not very good at controlling my movements and with my musat I usually just spoiled the sharpening with its corners (in fact, not being able to control my body well was the reason for buying a sharpening device, since there the requirements for a person are significantly reduced).
On the other hand, if we consider Japanese knives, then they have a very high hardness (easily more than 60 HRC), and if the burr was removed during sharpening (and this is achieved, for example, if sharpening angles are clearly controlled and finished with a stone with a fine grain , for example, the same Arkansas), then during work we do not have a bend of the cutting edge: the cutting edge from strong influences usually
crumble... And this is clearly visible through a microscope. That is, in my personal opinion, for the most part, they are used as a means of straightening the cutting edge; for knives with a high hardness of the edge, it is simply not needed. At the same time, if you use a musat with an aggressive surface (which sometimes resemble the most natural file), then it is quite possible to "remove" its sharpening from the knife.
