1. Several issues that novices should pay attention to

1. Knife sharpening is a job that requires patience, time, skill and even talent

Even if you use a fixed-angle knife sharpener, it can only solve the problem of a fixed angle (the most difficult technique to master in knife sharpening) , but all other requirements are indispensable. Patience, time and correct operating methods are still required to sharpen sharp and durable knives. Whether it meets the technical needs of sharpening is the best criterion for testing the quality of a knife sharpener, rather than judging it by simplicity or complexity. Quick knife sharpeners are the simplest, but their essence is scraping rather than grinding. The effect is very poor and sharp. The performance is close to rough grinding, but the retention is worse.

2． Using a fixed-angle knife sharpener is still inseparable from the relevant knowledge of knife sharpening technology

Using a fixed-angle knife sharpener to sharpen knives still belongs to the category of manual sharpening. If you are not familiar with the relevant knowledge of knife sharpening technology, purchase It is impossible to judge and compare the advantages and disadvantages of fixed-angle knife sharpeners at this time, and of course it is impossible to use it well.

3． The edge angle should be suitable for the purpose of the tool

An edge angle that is too small is not durable and is prone to curling or chipping; an edge angle that is too large is not sharp and is difficult to sharpen. Slicing knives are usually at 30 to 40 degrees, chopping knives are usually at 40 to 50 degrees, and boning knives are usually at 50 to 80 degrees.

4. Over-sharpened knives are not durable, so they should be stopped in moderation

Over-sharpened knives have too small an edge radius, lack of strength, and are prone to curling and becoming dull, so you must master simple edge blunting techniques.
